Players get 6% of condition every three hours. I know when this regeneration happens, I know when I play next match, so I can arrange training to make use of maximum energy and to have players fully rested before the match. But, today, I trained just after the noon, came back for evening match, and saw players not rested - because the regeneration time was different, moved forward by some two hours!
Why this happens? It wasn't first time, it happens quite often, few months ago there were few days when it seemed to change few times every day, so planning of training was almost impossible...
