31 DET is capped. You mentioned the price of materia making the IV materias unaffordable so I'm not sure if you realized you'd need savage might IV to reach 31 DET.

But to answer your question, and I may be incorrect, but you would only get +1 determination on your nexus using the build you mention. The rest would have no gain in stats once you upgrade.

Edit : Asked my friend and he corrected me and said you need 22 crit to get the +1 bonus but for determination you need to cap at 31. Hope this helps.
