For the question that Pulse asked:
First of all, the OU list is generated using data from the last three months (in this case April, May and June), not just the last month. This is why Milotic is OU.
Secondly, it's true that Wobbuffet was banned to ubers. However, I decided that its usage should also be used, because April, May and June statistics took Wobbuffet into account. The usages would have been completely different had Wobbuffet been banned... hence I can't just remove Wobbuffet from the list and find the cumulative frequency from there.
Admittedly, I actually did exactly that in the April list, but that was because Deoxys-S and Wobbuffet were both in limbo. Technically, when Deoxys-S was put in OU a few weeks ago, the last OU Pokemon in the ordered list should have been taken off, but I left it there to avoid confusion.
