so youre saying that as you get into higher level, the training slow automatically. example: training from strong -> prolific is slower than mediorce -> average?
No, I am not saying anything even remotely close to this.
Training is supposed to slow down relatively rapidly when the potential is reached, as opposed to the age effect, which is gradual over time, and height effect which is constant. Therefore, it's fairly easy to distinguish when a player hits t he cap.
