You will likely get varying advice on this. My opinion is, that would be better than blindly adding a fixed value to each cell, though of course still not ideal. You should be able to discern whether your driveability got better or worse as you ride it. Just don't change too many things at once.

If so, you may already know this, but that Default AFR map doesn't match any of the race or stock values I have seen for the Calibration Mode (Closed Loop Learn) region upper boundary. Starting at 5000/60 and higher loads, that AFR map declines from 14.7. But the default eeprom CLL upper boundary extends to 5000/90.
Unless you plan to abandon your O2 sensor after tuning, you want your afrbins to have 14.7 in the areas that encompass the Closed Loop Learn, and Closed Loop (CL) Idle regions in your eeprom image. Having smoothing on the borders of the CL regions is ok, but inside CLL, it needs to be 14.7.
Now if you're like me and don't spend much time cruising at that RPM, don't worry about it and leave it as-is. But I suppose some do which is why it's part of the AFV calculation. I'm mainly sharing this for education purposes since you seem to be in the thick of this and enjoying it!
