The only thing I wanted to point out is that they were not the same age. But does that matter? I don't know.
yes, age matters a lot
18-21 it's the same, then year after year, gaining is dropping
also stars matters a lot. The gaining of a 7* player is less than a 5* player.
Those are basics on training.



dependent on fitness ability.
of course, abilities are cosmetics - lol
