Penalties
Race 1
Dave O moved sideways into Simone, sending him off onto the grass at high speed where he slid back onto the track and took a few people out. That resulted in Shameless dodging right to avoid Simone, where he hit the side of Gratulin, turning him into another high-speed cannon ball. So it all started from a fairly innocuous albeit high-speed side-to-side impact, with drastic consequences. Because it was a side-to-side impact, no penalty.

Race 2
Dave O ran into the back of Seanus, spinning him and causing a pile up – 50 kg penalty ballast.

Race 3
Seanus ran into the back of Dave O, spinning him – 50 kg penalty ballast.

Thanks for the racing and the later start, means I shouldn’t need to come up with a bunch of reasons I need to leave work early on tuesdays...
First time I’ve raced on this track, it has a good flow, prety cool.. Race 1 was a nightmare being taken out at corner 2 and having the car destroyed, can’t believe how much top speed it lost. Race 2 and 3 were much better though :)

Looking forward to the next round
Title: Re: S20R1: Tor Poznan Post-Race Chat
Post by: Shameless_1 on December 19, 2017, 11:22:11 PM
I didn't expect to do well, had very little practice, managed only 1:43s and maybe a high 42 so didnt expect to do any better and be at least 4 seconds off pace. Did okay in the first race, saw a few offs and tried to stay out of it.  On the first left hander I saw poor Joe get caught up in an accident that 2 other cars had which sent him from the right straight across to the left of the circuit, I had time to change down and break to avoid T-boning him, lost a spot or 2 and finished where I expected. 

The 2nd race I was thrown up in the top 5 and tried to hold off people that were faster than me for as long as I could.. Watching good battles going on behind me  as I turned to defensive racing.  Finished around 10th or 11th I think or close to it..

The 3rd race I was tired and hot so I took it a little easier, some good racing by shayne and a good side by side battle with Wally. 4% restrictor didnt hold me up enough and had fun making my ass as fat as I could to make it hard without deliberately trying to block. I still suffer from understeer issues due to joystick, so i need to tweak the setup more.

Merry Christmas everyone and thanks for a good night.

Sorry for the hit Simone  :-[ hadn't even realized I'd made contact. And apologies to Seanus also, just about managed to pull up enough  :(

Should have a most carnage causeed award  ;D I'd be leading.  With 50kg next week most of the field should be safe ;D

In race 1 I copped a hit in the first lap incident which broke my windscreen and damaged my rear, but I don't think my times suffered at all. That race was a big struggle with Joe and Shameless, who I never managed to pass.

Race 2 was the three-wide squeeze into Turn 1 with Shameless and Killagorilla (I think). I came off the worst for wear when 3 into 1 didn't go, and came off onto the grass and hit the barrier, dropping 10 spots in the process. More close racing with Ab156 and Mael. I was lucky at the end when there were a few contacts and offs in front of me on the last lap, gifting me 5 spots to finish 11th.

Race 3 was a really good battle again with Shameless massive Beemer, Joe, Mael and Bacchulum. Lots of dicing and angling for position. It's entertaning racing, having to attack and defend at the same time. This time I finally managed to pass Shameless, on the last lap, after being side by side for a good part of it and not touching. Good racing.

Sorry I missed all the action. The internet kept dropping out. I tried several times during practice and qually, but finally gave up.

A safe and Merry Christmas to all.

That BMW is certainly not a favourite of mine, but racing was close and I enjoyed it.
The track was new to me and if I raced this car before I can't remember.
There's an accident with Grat where he pulled right in front of me probably assuming he already fully passed me. That wasn't the case and resulted in him going off.
Otherwise I managed to keep the car on track and stay out of trouble.
Thanks guys...have a Merry Christmas :-)

The server reports relative speed, but even that looks excessive! It doesn't really matter, because any impact over 100 kph gets 10% restrictor.

How are people getting speed out of this car? Are you running TC on or off? I left TC on as I find it a little too easy to oversteer out of corners with it off (as did Mael!). If you slide the car, you lose a heap of time.

That one was with the armco, so the speed had to all come from the car!

I think it's shift points.
I was exiting corners equal to others but being blown away by the end of the straights. :'(
With a fixed 'box, it's not ratios, and I just changed where Race Essentials suggested (7000rpm).
(TC off, btw)

You must have been hiding some nitro's in that car Bacchulum, explains why I could not get past you!  Sorry for the bump leading to the incident, just misjudged it slightly; but I really did not think it was necessary to accelerate into the barriers  ;D

Think TC off is quicker in this car on the provision you concentrate, I got a bit tired after a long day at work and paid for it in the second and third race.

Interesting you mentioned it. I haven't even tried TC off...thought it's useless.
Will do for the next one.
However, I did make changes to ride height, toe, camber and dampers.

Hmmmm, I might experiment with camber and ride height. I left those at default values, thinking they'd be good enough by default on a race car.

Shift point and gear choice. I watched phil do a couple of laps of monday night and copied him and found nearly 2 seconds.

Shifting much earlier. Before i was red lining it now im shifting at the first red led on my rim which is only half the ledss. No idea what rpm that is.

Also staying in a higher gear seemed to help. There were only 3 turns where i went down to 3rd. Final turn where i was getting a good run on people was taken in 5th.

It seems to me that carrying as much speed as possible with minimal sliding through corners is key, possibly early apex also allowing higher speeds on the straight. So fine tuning a good set-up will probably help although I'm not that good at any of these points just mentioned. Speaking of setup the race server has always seemed different to the practice server for me, not temps or surface, but possibly weight distribution or something. I can set up a car to have say approximately 3degree camber (displayed in the overall section) by way of ride height and say - 2Left, - 1.8right in the set up. But load that same set up in the race server and it's all out of wack and to achieve the same approx. 3degree I'll need to be - 1.5left and - 1.7right. (just approximate figures for example).

R1 wow kaos, managed to get by without incident luckily, feel sorry for everyone else who got caught up in it. I had a car, have no idea who, fly past me into a corner almost like as if they couldn't see everyone else's brake lights on and possibly forgetting they had cold tyres. I didn't see what happened to them because the big incident unfolding in front of me which I needed to avoid. Ended up good racing trying to get past Russ and Bach, Russ made a mistake attempting to pass and gave an extra spot.
R2. Held decent pace but could not find a safe way past Simone, others like Phil and Kceneder managed to get by me and Simone though, good fun...
R3. Lonely...stuck in between the lead pack and everyone else.

As far as cambers and ride heights go, just be wary bueller.
The figures given are in relation to the ground, so if the ground isn't perfectly flat you'll get erroneous readings.
This normally explains the difference between the practice and race servers.
On the practice server you normally spawn in the last pit box but on race night you'll find yourself in a different pit.
And seeing as pit lanes are very rarely 'billiard table' flat, you'll get different readings.

Race 1 I got tangled in the lap one incident which left me facing the wrong way on the grass and from 8th to last. Caught up and passed a few cars.

Race 2 got caught in the accident again and was in second to last. Again made up some places. Last turn of the last lap was at the back of a pack and hit Matthew's rear side panel. I didn't expect it to slow up as much as it did on the apex and it caught me off guard. It also caused people behind me to hit me; all my fault so sorry to anyone involved.

Race 3 went pretty well with some decent close racing.

Was wondering about the set up reading different myself, my front cambers were showing WAY out compared to practice server, left them alone as figured it’s a ground thing but haven’t seen it out like that before anywhere, was over a degree out in front left. Couldn’t get within half a second of my prac time weirdly.

As for speed, defenitly shift early, if you look at the torque curve on the car it peaks very early and drops very hard at the end of the rev range. TC off, throttle control and a bit of alignment/suspension tweaks to try to help corner exit, the huge low end torque makes it really easy to light up he tyres

See my penalties explanation in the first post. It all started from a side to side impact between two cars and escalated from there.

That explains a lot, thanks. I thought the readout would be as if it was sitting on a wheel alignment rig and that one server accounted for drivers weight and the other not (or something like that)...it should be on a wheel alignment rig imo lol

All good, we were behind the incident, I made it through safely, but not sure about the other person I mentioned. I'm here to race not so much win, so I'd rather play it safe in most cases

If you're in doubt, what I do is go to a modern F1 track, KS laser-scanned, ie. Silverstone or Spa, as the FIA have enforced level pit lanes recently. ;)

I had a great nights racing in the BMW.  I copped a couple of hits and i gave one or two small ones but all up I don't think I have raced so
consistently close for a long time.  On the setup front I decided that I can't make it go any faster in a straight line so I ended up changed most things
just a little bit do get it nimble in the corners and with good power down.  You cant afford wheel spin in these as to much time is lost.
All up looking forward to a good season although I will be missing two rounds.

Wally: Can you put dates on each round in the sign up?  I heard mention of no race next week.  (Disregard, Just saw the post)

All the best to everyone for Christmas..... Cheers!

    Lap 12: 148 kph (+10 restrictor)

Hi Wally,
Please note there is no suggestion of blame on anyone here, just questioning the contact speed reports.

When I saw this I thought straight away the lap 12 contact was wrong which it is, so I had a look through the replay and these are the contacts as seen in the replay.

It looked to me like I had 7 contacts in the pileup but you have listed 6. A couple looked very light so maybe one didn't register. The rest of them:
    Lap 1 : Mael 58 kph hits me doing 36 kph - This seems like it should be a 22 kph contact.
    Lap 1 : Me 44 kph hits Dave O doing 22 kph - 22 kph contact
    Lap 1 : Me 48 kph hits Joe doing 23 kph - 25 kph contact
    Lap 1 : Me 41 kph hits Seanus doing 20 kph - 21 kph contact
    Lap 1 : Joe 41 kph hits me doing 37 kph - 4 kph contact
    Lap 1 : Mael 45 kph hits me doing 37 kph - 8 kph contact
    Lap 1 : Mael 41 kph hits me doing 25 kph - 16 kph contact
    Lap 12: Me 46 kph hits armco doing 0 kph - 46 kph contact

I think this would have given me 3% restrictor instead of the 48% I was given.

Now I know it's not always as simple as the difference in speeds. The angle of the cars etc can make a difference to the relative speed of the contact, but the numbers are really far removed from reality. e.g. Lap 1: 108 kph - even if you added the car speeds as in a head on collision it doesn't add up to that much.

I have no issues with the idea of restrictor for contacts but would you mind having a look at this as it seems to be more like random numbers when it records a contact.

Bit of a hard one for me here, managed to get the car reasonably setup but not quite on the pace of grat. Race 1 i stayed behind phil all race, managing the meds early on which helped me towards the end of the race but it was too difficult to pass especially when the pace is equal lol. Race 2 was going ok but my progress was hampered by just being in the wrong place at the wrong time lol and then got spun on the final turn so i finished 17th i think. Race 3 much of the same but then got caught out on the curb of t1 trying to get simone and clipped him as the car slid so sorry about that simone, finished 12th i think so could have been worse considering i was put to the back of the pack after the incident.

I think contact penalty’s need to be severe. If you rear end someone mid corner even at 20km/h because you brakes too late you will likely spin them and with a short sprint format that will ruin their race

Hi Wally,
Please note there is no suggestion of blame on anyone here, just questioning the contact speed reports.

When I saw this I thought straight away the lap 12 contact was wrong which it is, so I had a look through the replay and these are the contacts as seen in the replay.

It looked to me like I had 7 contacts in the pileup but you have listed 6. A couple looked very light so maybe one didn't register. The rest of them:
    Lap 1 : Mael 58 kph hits me doing 36 kph - This seems like it should be a 22 kph contact.
    Lap 1 : Me 44 kph hits Dave O doing 22 kph - 22 kph contact
    Lap 1 : Me 48 kph hits Joe doing 23 kph - 25 kph contact
    Lap 1 : Me 41 kph hits Seanus doing 20 kph - 21 kph contact
    Lap 1 : Joe 41 kph hits me doing 37 kph - 4 kph contact
    Lap 1 : Mael 45 kph hits me doing 37 kph - 8 kph contact
    Lap 1 : Mael 41 kph hits me doing 25 kph - 16 kph contact
    Lap 12: Me 46 kph hits armco doing 0 kph - 46 kph contact

I think this would have given me 3% restrictor instead of the 48% I was given.

Now I know it's not always as simple as the difference in speeds. The angle of the cars etc can make a difference to the relative speed of the contact, but the numbers are really far removed from reality. e.g. Lap 1: 108 kph - even if you added the car speeds as in a head on collision it doesn't add up to that much.

I have no issues with the idea of restrictor for contacts but would you mind having a look at this as it seems to be more like random numbers when it records a contact.

Cheers

I'll take a look at it. If the contact speed is consitently overstated by the server, I can half it for example. But then this is all arbitrary, right? I have arbitrarily said 100 kph = 10% restrictor. It could be 5%, or it could be 20%. The point is, the more contacts you have, the more restrictor you get.

When I came up with the figures, I actually looked at previous server logs, and looked at contacts and categorised them by speed. As reported by the server, most contacts were at the 30 to 40 kph mark, and then the speeds tailed off from there.

But I'll take a look at it.

I had an hours practice on Sunday which was a nice change and found a reasonable balance to start with and then did my first laps on the track on Monday night. Tweaked it a little and was feeling pretty good. Got to qual and was nowhere and curious as to why. At then point I realised my complete blonde moment and swapped to medium tyres.

I managed to avoid all the race 1 carnage and was pulling away from the cars behind when I put 2 wheels in the grass and lost it. Back to the rear I went

Race 2 was a lot easier starting from 2nd on the grid but I figured the quicker guys would catch me from about mid race.......which they did. I fought as hard as i could but as fair as I could and it wasn't till the car started stepping out on the corner exits that I just couldn't hold them off any more. Finished 4th which, lets face it, is like a championship win for me.

Race 3 was going to be a lot tougher and I made it worse by getting on the grass on lap  and rather than trying to re-jion and take out half the field, I waited for the field to go past and the spun the car before re-joining. Managed to make my way back to 13th so was pretty happy for the night.

I really don't like these cars but I do like the close racing

Thanks for highlighting this Russ. I did some analysis of the impact reports compared to the replays of the three races, and it looks like the server speed is exaggerated by a factor of about 4.5x. So what the server reports as a speed of 36 is in fact more like 8. What that means is that instead of penalising impacts from 30 kph to 100 kph, I'm penalising 7 kph to 25 kph.


But I originally chose those speeds because most impacts where between 30 and 100 in the server logs (with most around 30 and then a decreasing number down to 100). So whether it's speeds of 7 to 25, or 30 to 100, I'm still penalising the impacts on a sliding scale starting from the most common impact speed.


So I think it's OK as it is - it's just that the "scale" is different. Think of it now that actual relative speeds between 7 and 25 kph earn 0 to 10% restrictor.


In the replays, in the blatant rear hits which look pretty bad in the replay, the relative speed of the cars was about 25 kph, so that scale seems reasonable.


For further perspective, when Simone cannoned into me like a rocket in race 1 in a crash of rare high speed, the relative speed was still only 60 kph.
