So mapping the fitness loss and ability gain in games is definitely next on my agenda.
playing in old version :
A 5* fast trainer in 3 bars, practice match, is gaining about +100%/ 1sp (4 skills of new version) with -18% condition loss
In a game he 's gaining about + 130%/1,3 sp (about 5-6 skills of new version) with about 22-24 condition loss.
