I don't know about much of the stuff posted in this thread, but I think that the change in the attitude of posters definitely shows a change in how crepi acts. The last time I played with him (2 days ago) he was on SuSurfiT.
He would spec any new surfers who asked for help (including me) and give them honest and helpful tips on each level.
Between requests, he would try to do the surf level itself, but even if he had made dramatic progress he would still invariably go back to spec to help out others (thereby trading away his progress).
I don't think it was ever in question that he is a good medic, but now you can be sure that he is also a cool person!
