How to train your players properly after the update

That was before the latest update.
Now a grey skill of 40% gaining a double of a white skill of 140%.
If you have a new player with about equal skill, yes.

Nope, with Arnts and The Piggy In The Middle training I tested it. He got 1% in grey skills and 2% in white Skills. Even though Aggression (grey) was the first one that got +1%, before every other skill.
