I saw your post about the max EVs in that one thread, and just wanted to clairfy (since it seems that my response in there got a bit lost in all the posts):
252 is the max now, whether you EV train the old-fashioned way or via Super Training. I recently EV trained a Goomy via hordes, and its EVs didn't exceed 252 (because I still had 6 pts leftover, and I'm pretty sure I accumulated more than 252 EVs worth while training).
