Ok, there are few days now, when I set the team (all players 21-22) in a six-pack of the easy/very easy drills of 3 categories (-,75 condition loss) , I also get the X2 bonus, but the team cannot fill the 10% of Attack and Defense bonus. \
It needs a little more.
Weird with this pack of drills and the X2 I could get the 10% in all categories.
(I 'm talking about two active teams I have, not only one).

Anyone else ?
