well, it compares to other players of its value. I had a 21 year old player that gains up to 50 on stretching and 180 on real match but costs 1.63M (note that this is already a big amout for me level 3) . But i bought a 18yo player with 3.2M and i thot wow that must be a super fast trainer but it turns out that he learnt things only a bit faster (185~190). So imo when high valued players should be fast trainers, it does not mean that the training ability is proportional to their value and their quality only.

hmm and im not a token buyer. i buy these trainers using half of my money and hope i can flip them for a profit so i could buy better players next season.
