i do that deduction based on everyone's highest youth player this season get a playstyle.
but tbh my lower % 19yo have more playstyle points atm because i keep training him since he's just 4* early on, now he's 6* and automatically be in startin11,
last season he's just a reserve. and almost unlock intermediate already 3/4 of standard 1500 points..
I have 6 playstyles unlocked. The one that was already unlocked at the start is growing more quickly than the rest, he is 19. But I have a very good AMR with lowest % among the starting 11, but is the best scorer in the team and he is 26yo, he is gaining playstyle points more quickly than other younger players, 18,19, 21.
I feel more playstyle points are given to good performers and maybe to fast trainers? I don't think age is the most important factor here.
