Realistically, I think you have as good of fuction as anyone after a total proctocolectomy. You seem to be doing very well. Typically, 4-8 bowel movements per day are to be expected. To expect or strive for less than your 2-4 is not advisable, as that can lead to bacterial overgrowth from fecal stasis.
It is impossible to tell what sort of ileal pouch you may have by looking at yourself externally. A pull-through procedure may mean anything from no pouch to an S, W, or J. S and W pouches were more common a few decades ago, but the j-pouch was most common 15 years ago. So, it is most likely you have a J-pouch. S-pouches are more likely to have emptying complications as time goes on, and it does not sound like you have that.
