Here's a better question that other people have left a lot of info out to be desired:
2 position training:
My example: One guy got 40, another 43, another 4, another 0, two at 48.
two at 48 one got 50, other 53.
So...here's the million dollar question knowing all six players really could use the training equally.
Take 4/0 start them to play 48 OR take 4/0 start with 40/43 backing up knowing that 40/43 will likely play 60 some minutes?
I would lean 4/0 full game, but the advice from the manual seem otherwise, but I don't think correct unless we are talking about like a really really steep decline, which mean partial training is completely worthless and thus either way I go only 4/6 of players will get training. I doubt that's the case.
But the manual seems to promote going 48+ as in more than 48 is even better than giving partial to others...
