Q: Stepover for tapered ball mills

I use several tapered ball mills for 3D carvings.
When setting up the actual geometry the stepover used in the toolpath is based on the flute diameter (for mostly equal to the shaft).
To get a correct stepover, would it not be better to be based on the tip (if not zero)?
Haven’t tried it yet, but I think the same applies to v-bits with a not-zero tip…
