I agree with this. Most people just think that percentages should be proportional, but that is obviously not always the case. If I played the same amount in December that I did in November (1000 games roughly, apparently, much to my shame) I have seen electivire several times. Do I believe that it should be OU? No. Do I believe that it is OU? Sure. And I think Chris is taking the credit for flygon and empoleon because he wrote up the analysis of empoleon and made a thread on stark of the supposed "awesomeness" of flygon. These threads can easily influence enough players to try it out to make its usage rise notably (see colonel M's rhyperior). It's pretty much a given that if a popular player uses a Pokemon it's usage could rise, I could think of several of incidents like this.
