I dont have the data on this computer but if I remember correctly the JS-training was still at 20y then 6 IS and 3 1on1 at 21y.
I suspect that he probably capped in the middle of this training. Two weeks of JS should have brought him close to a pop, then the 3 weeks 1on1 should have finished it, even with his age and height (not to mention the 6 IS). Did he pop in IS during those 6 weeks?
