My personal opinion on how Id like to see something like this tested :

Ideal would be if you could post two AVIs on the web resulting from two pass
encoding with/without adaptive quantization, if you can find a situation where
you can show noticable visual gain from the adaptive quantization that is.

Alternatively/additionally two fixed quant AVIs with/without adaptive
quantization to show it can save bits without detiriorating the quality, ideally
with a third where you try to approach the size of the one with adaptive
quantization by using 1-pass quality while tweaking the quality setting.

Images from such comparisons would do if you cant put up AVIs anywhere, but
images tend to lie :)
