I understand your point, yet I doubt the effect of training GS on high level players.
Meaning, players who already have GS of respectable or higher.
I had a complaint from a guy who trained GS and had players actually drop from proficient to strong, or from strong to respectable. Actually he didn't see much diffrence with training other trainingtypes.
I guess GS training works when you have players with lowes GS, or players who had to many, or to few minutes. But I don't think you can prevent your players from having respectable GS when training GS... so... unless your players are in bad shape, I don't think training GS will do any good...
I never trained GS myself though, so I might be wrong?
They are not your friends; they dispise you. I am the only one you can count on. Trust me.
