What you mean by this? I've trained GK alone using Skill Drill and gained Concentration. Whether or not the other skills go to waste or does the keeper get -0,75% worth of Concentration, I have no idea.

To me it seems like training several players together only makes a difference in gaining bonus, nothing to do with gaining skill points.
