Maybe some of are not affected this, in my team case, I attend or absent during the game whatever I do match result go through by game engine only, the only benifit we will get by watching my match is, 1)substitution-this effects very rarely, 2) Red card- we can fill the minimum needed player if our player got red....
Some teams are not training their players regularly but they still manage to win everyday, by this way what's the use of training??
And one more thing I want to say that I'm doing these experiments in official match, not in friendly matches,
