When game time overlaps with the instance that players' condition recovers, condition recovering will be delayed until the game ends. For such case, to avoid wasting condition, I usually manage some of my reserve players' condition to be around 94-95% instead of 99% right before the game.
This results slight disadvantage in competition, but it is not too big deal for one game.
However, fixtures of a team are often arranged 3 hours apart. As a result, the above competitive disadvantage can occur for 2 consecutive games. I shall face this tomorrow. I will be glad if Nordeus consider this suggestion to avoid unfair competitions.
