Yes it's difficult because it all happens between 3 and 3.4 volts when you only have 2 point on the curve to manipulate. I could try and richen up 3.4 a notch, but I am guessing it would create another problem.

You mean instead fix it in open loop fueling so that AFR becomes correct and AFR_Command has the tops and valleys instead?

Yes, that's what I meant with locally more power. But once the wheels grip again I would assume the subsequent data would then be calculated as a decrease and looking over a bigger part of the graf RPM would build slower because time was wasted spinning the wheels?
