Here is another recent thread with the same subject.

but to be honest, it didn't make me wiser as yours too.
I mean, what is the difference in a highlighted skill with a non h. in a training ?
What 'll be if you put a DC in a training with the the drill "Sprint" (hard) which has speed and with the drill "Press the play" (also hard) which has tackling.
Will be there a difference in gaining ? How much ?

( for example learning your MR to be a MC will be more difficult than learning your MC to be a MR)
I don't understand that.
Learning a new position just needs 50 skill points.
