You mean within one season compared to a level 4 trainer?
yes, you understand right:-)
When I see I don't see the difference I mean, that I don't see a significant speed up in training. Yet, I do believe that it is faster. I just think that it is still possible to build a U21 player with a level 4 trainer.
of course my friend you can not see a
significant speed up in training, because like you see here
http://buzzerbeater.wgz.cz/coach-height-and-age-affect it's estimated in about 0.06% and like I say before it just about 2 week's of extra training, but for a young U21 prospect it is something:-)
To give one example (okay, its only a half example): My PG Hampsas was trained with a level 4 trainer. He didn't make it to the U21, but, according to the salary he was "better" than some other guards on the team. I think if I had trained him a little differently he would have made it.
ok, so you example is not so good, because you player it is not in the squad :-)but it's a nice player! What I can also say is that the salary it's not a very good indicator, because they are on the TL a lot of player, that I can not post here, with big salary and without a good arsenal of skills(monoskills)...I mean, the salary can't show exactly how good it's a player, because they are skills like JR, JS,PA, that can grow player salary, but not improve so much his performance.
