Let's say that individual training gives you .8 increase in a skill for 3 players trained a week which would equal a 2.4 gross increase in skill for the week (of course only for those 3 players).Would these be comparable?2 player training - .4 increase for 6 players = 2.4 gross3 player training - .25 increase for 9 players = 2.25 grossteam training - .16 for 15 players = 2.4 gross.All these numbers are guesses.
