So some folks know I've been doing some research into the way that AR and NR works. I've been quietly watching threads such as these, and see a lot of incorrect/incomplete information.
Anyway, I'm made a lot of steps towards figuring this out (in fact, I suspect I have the basic idea down), but need more data and test cases to confirm and flesh out what I have.
There's been a few folks helping me, but as they say, many hands make light work.
If you're interested in helping, shoot me a PM. If you have theories on how it works, post them up, and we'll see how right you are. :p
