I'm learning to fly like that. I started by standing on a chair and flying to the ground. I'm working my way up to jumping off the top of the Empire State Building.
Oh how humorous we are .... but thanks for proving my point. If you practice flying by increasing 3 feet at a time, at least we learn how high you can fly. With ABX testing all I see is a bunch of people jumping from different skyscrapers - all with the same predictable result. That is why you don't learn that much, except what you already expected.
Remember the only thing you can absolutely learn from ABX testing is that if you pass you were absolutely NOT guessing (down to extremely unlikely probability). A fail tells you close to nothing - A could have been Bach and B Mozart and maybe the listener was just not paying attention.
I like how you went from first timer in ABX, to telling us what abx can and cannot do in a week.

I would think that most people here have a little understanding of statistical significance and have looked at most of Arny's explanations about the ups and downs of abx on his website or now on hydrogen.
anyway the logical "solution" for you then if you're looking for positive samples and progressive evaluation, would be to try abx starting with 6 or 8bits and go up. if all you're asking for is when does the quantization noise is audible or when is the track eaten too much. but we already have a pretty good idea about that, it would be a little under 10 or 12bits for most people at normal listening level. which was about what we had when 16bit dacs where only 16bit.
but as RRod said, it a matter of what you're trying to achieve with abx. looks like you're trying to find any way to succeed, your not trying to know if you would succeed under normal conditions. just get the volume loud enough on a calm enough passage and you'll win 100%. the end.
but that's as fake as trying to show you can hear 20khz by pushing the tone at 140db. sure you can succeed the test, but what did that tell you that you didn't already
