I know it's been a while since you posted this thread, I didn't get to read it until now. You seem to have the right idea, I'll just say a few things.

- You said that "clearly" 3-betting from the button is better than other positions, this is patently untrue. The BB is by far the most profitable 3-betting position, followed by the SB, then button. This has mostly to do with the fact that you are dealing with much tighter open ranges from the cutoff or earlier positions, but also because you are laying a somewhat better price on the steal. Also you are last to act, and people tend to call instead of 4-bet when they have position, so you get more postflop value.

- I also think that your assigned folding frequencies for the cutoff opener and the blinds left to act are far too high. At mid-stakes my 3-bet success from the button is barely over 50%. I'm sure at the micros it would be significantly higher than that, but definitely nowhere near 84%. I would guess the average is around 60-65%.
