You may have confused Game shape training and other training.
Game shape training has a diminishing effectiveness, anyway its always a chance of success you may see a good result or a bad one. You have to wait four weeks for it to return to a normal chance of success.
All other skills do not behave like that and, as @perpete said, only the elastic effect changes the expected return of training.
