GS training was tweaked a few seasons ago. As far as I remember, from that change on if you train GS many weeks in a row, the effectiveness of training diminishes.
P.S.: I agree with you this detail about GS training should be in the rules.
P.S.2: Do not train GS. Manage your players' minutes. Unless you are playing B3 finals or something. But by then you are supposed to have mastered managing your players' minutes. So just don't. Train something which is going to add long term value to your players.
