There are riders that I'm slower than, and once they pass me, I rarely see them until they sit up to do a cool down lap
Then there are riders who seem to start/finish a lap within a few seconds of me, but often times do better when I (and my body mass) ought to do better, and do worse when I (and my body mass) ought to be the one suffering. No idea who deviates more, and how much.
