It used to take only 4 training sessions for all bonuses circle to get filled. Now taking a lot more sessions. Anyone knows why this is so? Is because of the higher training level?
[Now on Training Level 73. Normally trained a team of at least 10 players of all positions (my normal XI for my 3-2-1-3-1 formation) 4 times through 6 drills: 2 from physical, 2 from attacking, and 2 from defending to fill all bonus circles.]
