If player condition recovery time overlaps with time of a match, it will be delayed to the instance that the match finishes. Players with full condition cannot enjoy the condition recovery. If the the condition recovery time is delayed to 15 minutes after the match finishes, there will be enough time for arranging training for these players to use up some of their conditions. Then they can also enjoy the condition recovery.
It is fairer. In last season, my team had some consecutive games that condition recovery time overlapped with match time as both of them are 3 hours apart. I accumulatively lost many skill points.
