Category enforcement C group

Category enforcement. Just got finished with a race in the C category. Race was fun. Not a big deal but was curious how the winner is allowed in the C group when he rode at 3.8? I check his profile and that has been his deal. He has won most of his 10-15 races at 3.7 or 3.8. He should solidly be in the B group. Just curious how this is happening.

Probably raw watts limit - To be a B it’s 3.2 (3.34 in reality) and 200 watts minimum
