Upon what do you base your assumptions about the various training speeds?
I may be able to go along with 70% for 2 position, although how do you arrive at that precise figure, and not say 75% or 80%?
The team training figure also looks questionable.
Further, if you are going to allocate 3 players per position on the "specialist" trainings, then for the sake of fair comparison we should do the same with team training, which means 15 and not 12 players getting training.
