Great idea, thanks for the effort.

First hypothesis:
The higher Fitness skill, the less Condition Loss (CL).
So far I was with Al Svandberg on this
-I see zero correlation between -- individual -- fitness ability and conditioning loss in a game.
One impact of the Fitness Ability can be that a player plays better with a high fitness ability if he has low conditioning, IE that a player for example with 200% in fitness ability will perform better with 50% conditioning than a player with 50% fitness ability and 50% conditioning.
Interesting if you can prove or disprove your first hypothesis.
