My apologies if this is drifting too far off topic, but hopefully it'll be helpful.

You should actually have two kerfs. Imagine cutting an 8" root and a 4" tip as an outer panel. If both are done in one minute then the root is cutting at 8"/min and the tip is cutting at 4"/min. The wire temp is constant thus the overburn (kerf) will be greater at the tip where the wire is going slower. I use GMFC for software and it has two kerf values in the setup to compensate for this. You'll need to figure out how your software deals with different kerfs on tapered panels. The higher the taper the more evident this is.
