That's the thing about collecting data - I don't just "think" 63kg would be a good figure, that's what the data shows. If I didn't follow the data, I might as well say "Matthew got the most points in season 13, but really, I think Guybrush should have won, so I'll call him the champ". Sure, the Corvette will be slower at some tracks and faster at others, but so will all the cars.
