When a player gains experience on the field, he also learns faster from training. The longer the experience, the more effective training becomes.

It might be a good idea to add experience to the training coefficient. 0.01x for every 1% of experience.

All players have a base starting value of 1.00x. Then this parameter increases as the experience increases. So if a player has 4% experience, he will receive 1.04x in training. A player with 100% experience will receive 2x

I would rather make the exp level  infuence on skill boost in matches

0-9 % exp = 0% skill boost

10-19 % exp = +1% skill boost

20-29 % exp = +2% skill boost

...

90-99% exp = +9% skill boost

100% exp = +10% skill boost

bad idea
