Yes, the regeneration cycle is 48% everyday.
For player and team bonus to max 10%, a minimum of 2 x 4.5% (6 very easy drills) training run would be needed, and trained with ads (other thread has explained it well). 9% spent.
If we use low pressing and zonal every game for around 20% loss in conditions each game, then conditions should always stay around max after a 1-day cycle.
However, there are always some tight games (us and opponent are only a few % apart, or even superior to us) that are must-wins, say a CL or Cup knockout round, that we would need to adjust to high pressing (to chase a goal) or man-marking (to try to prevent a goal against). We would need to then recover our first-11 by greens.
And needless to say, for association matches that we need to win (say a 8-8 points asso draw in the first tie, then we had to play a match before losing conditions for 2nd tie), then may need to use greens as well. Asso mates would be furious that we would lose a tie by a late goal in not using a few greens to recover properly (although we will never admit it and just blame on bad luck if it happens)
