Well, for one, because everyone keeps telling me I need to compare files of (roughly) equal bitrates in order to judge the effects of aq=2 properly. :)

I don't really target for a specific filesize/bitrate. The only time when I'm concerned about it, is times like these, when going to aq-mode 2 makes the output file so much smaller, even at lower CRF. If someone were to come out and say: "Don't worry, aq-2 is supposed to use less bitrate!", then I'd be happy too. Could simply be that auto-variance truly is that much more efficient; but I'm not knowledgeable enough in these matters to convince myself of that to the point of not worrying about it. :P
