I believe they changed APoC completely in order to fix blizzard's APoC, but it is all theory right now, not enough controlled testing.
Before blizzard had .0125 proc. so if you had 30 APoC you would get .375 AP per crit, the problem is that is always rounded to 0.
So the old method was:
A single crit returns [proc%] x APoC (like LoH)
New method is
A single crit has a [proc%] chance to return your full APoC. (kind of like Critical mass)
The "average" should be about the same, but it doesn't work out that way when you approach 50% crit rate I am thinking.
I disagree. If you cast blizzard you see a somewhat gradual increase to your AP regen. To me that indicates an AP gain of AP*Coefficient, though it might round it up to 1. Instead, if you apply your idea for the new method, you would get a spike every couple casts corresponding to the very small proc rate, but would mostly see no differences in AP regen.
It's actually pretty easy to test with blizzard. Just stand on Ghom, drain your AP pool, and cast one blizzard. Then time how long it takes to cap your AP. Then repeat a couple times. It should take about the same amount of time each attempt. Otherwise, if one attempt is much faster than the rest, that would confirm your idea.
I mentioned I messed around with AO a bit. I never noticed my AP shooting up really fast, which should occur if your theory is right. Instead all the AP returns were fairly gradual, which again indicates the APoC return is modified by the proc coefficient.
02/17/2013 03:05 PMI think what's going here is people are forgetting how much more geared wizards are now as compared to before in previous patches, at first we needed about 30% cc and that was it, then we needed 40%, then we needed 2.5 aps now it's 2.73 aps and 50% cc, all of this was to achieve permafreeze, no one ever thought about the fact that our cc and aps has been going up so much that maybe we didn't need as much apoc, because we always needed at least 20apoc. I think with as high as our current cc and aps is, it has also effected or arcane regeneration to where we no longer need as much apoc.

Again, I disagree. We had to gear for high APS and CC for WW to gain AP per cast once the coefficient was reduced. If you see the math I mentioned above, in my test I used some 87 AP per second and should have only gained 50 AP per second, well 60 if you include the base 10 regen per sec, yet my AP was full the entire time after wind up. That means I was regenerating AP faster than I should have been based on our previous assumptions of how APoC worked with WW.
There are a lot of cases pointing to crits not working with WW in the same way that LoH does. These cases all indicate that something is going on that we don't completely understand, and the APoC now seems consistant with those results.
