@gamer5289 is right
training has two hidden/unknown effects to new or not experience players.
Managers who were doing power-training with the old version, are familiar with that.

- one is the blue bar of refilling one old skill point
How close is to get the next sp

- the other is a mini roll dice in training.
For the same set of drills (lets say 5 hard = -15%) , one player could loose -13% , one -15% and another -18%.
The last one will also have little better gaining from the others.

So it's not wasted condition loss.
