Laz often makes extremely valid observations and other times he doesn't. In fact, he reminds me of just about everyone that posts on the BBS in that respect.

Many times his presentation harms his case a bit but nonetheless I regard him as a knowledgeable observer of the online ACM game situation. In short, I don't always agree with him, but I always consider what he says.
As for numbers... my non-scientific observation is that the CT has gained about 2% with the latest change. It used to run in the 7-8% range of the MA at the times I usually fly now it's closer to 10%. So, it's up a bit. If the MA dropped off much at all, it's probably just this 2% that are giving the CT a shot now. In other words... negligible change in the MA, up a bit in the CT. Good thing, overall... everyone should have options to make their gameplay more satisfying.
Just my .02.
