But I would have to be able to compare it with the results of someone who has a level 4 trainer and trains the same skills I do with comparable players. If you say he will be about 0.06% faster, how long would it take me to have adequate results, and how could I measure the sub-skills? I don't want to bother myself with figuring that out:)
Don't get me wrong, I still think he is worth it. I just think it is still possible to create a U21 player with a level 4 trainer (for example with a player who has an ideal hight and really good starting skills).
