there is so (to) many factors in training...
age, height, trainerlevel, played minutes (you never able to train perfect), how many positions you train, skillcombinations to match multiskills, and now even the potential, which makes it even worse you dont (i?) even know how far you can train your players and this might brings a big disadvantage of course you could have reached the maximum already and dont realize it for many weeks, which makes your training worthless...
what do you thing is the training system to complicated or is it just to soon within the game the we have to find out how everything works first?
