I had 8 hours prior to FSP (4hrs in a CT-4E) and felt in was invaluable in terms of familiarity with the airborne environment leaving more head space to deal with the challenges you are thrown. Just my opinion but I would deter anyone from stopping at 19.9 hrs as it would seem to show that you are, in a way, taking the "easy" option of getting onto the basic course, something they might slam you with at the OSB. They are quite similar anyway, just a couple more sorties in the CAP-10 for the advanced mob but in saying that, they do expect more of you. Depending on who's on the course, I've heard of people being placed in the advanced course with only 15 or so hrs.
