For AFF , the maximum amount of jumps we would allow in one day was three.Sounds a bit like the AFF route (although it's not, I know) in that you get taught a lot of technical stuff and techniques.
What you're not taught is survival and to think for yourself. Hopefully the SF candidates already have that ingrained from other things they've done. Odin knows the average AFF stude hasn't got the foggiest.
Seriously, with all the pre jump training, actual jump, debriefing and lessons learned,pre jump training for the second jump etc etc.
Throw in the adrenaline and utter awesomeness of whole thing and the student brain retains 15 - 20 % learning after this point.
Best to chill out over a couple of beers with fellow sky gods - and go and do it all again tomorrow.
