I did an experiment w/ the RB auto adaptivity. I did a screen capture of the AA values then reset the values in the AA table to all 0's. I then rode the bike for 250 miles under varying circumstances (fast, slow, twisties, slab), varying the RPM's from 0 to 10k RPM and using as many different gearing combos as possible
I was surprised to see that the tables rebuilt themselves virtually identically in both cylinders to their pre-reset values. The reason I was surprised is b/c I saw some areas (particularly @ low RPM) where adjacent cells had widely varying values (+12 next to -3 for example).
It seems to make most of it's adjustment from 5400 to 6200 RPM @ 10% to 20% throttle...smack in the middle of the midrange.
I also tried shutting AA off. While I can't say it was a and night & day difference...it did feel better w/ AA on. So my conclusion is that it works and works well. It won't turn a 200 HP race bike into a city commuter, but it does smooth things out nicely.
