Do you mean about those cases or development of skills ?
In that case, the level of the drills (high lv drills with 3 whistles or world class) probably matters.
No both actually, likt its not unusual that I have run like a 15% session 20 times, and the actual conditioning loss has not been 20x15=300, but like 275 instead.

Like these sessions I ran:

The conditioning loss should have been 32x15=480. But instead it was 454 (the line at the bottom shows the conditioning loss for each session, and down to the right is the total conditioning loss shown). Not a big difference, like 30 rests instead of 32. I am not sure how much of a factor this is, if its random etc. The actual loss seem to more often be lower than the predicted loss with younger players. But I got no real track of this, just saying that it can be a factor.
