Actually it does. You're making it sound that it only matters when you get a pop in order for training to take affect in games. A player with a skill level of 8 isn't the same as a player with a skill level of 8.9. As if sub-levels don't count for training or in matches. Therefor i'm saying you're making it sound less than it seems.
Actually it doesn't. If a coach 5 trains X
levels in 20 games, a coach 7 will train you (X+1) levels. You can slap this on a stating level of 7.1 or 7.9 with no difference whatsoever.
You can call it 1 level in 20 games, 1/2 level in 10 games, or 1/4 level in 5 games -- that doesn't change anything, and I personally don't think that it makes it any worse or better than it is.
And what about the sub-skills?
I imagine you mean secondary skills. 7-8 weeks is not 2 times longer than 2-3 weeks. It's 3, maybe 4 times. My personal experience is that unless you're training some form of driving or jump shot, the secondary training effect is negligibly small. Well, 10% of negligibly small is even smaller.
And my main point is that it's an objective calculation -- a statement of fact. That's how much it is. If it sounds small to you, maybe it _is_ small.
