Do 45 RPM records need higher anti-skate setting?

I was playing one of my 45's today and heard Distinct mistracking on one channel only. I increased the skating setting and it was much better. This was only near he beginning of the LP. The LP was a Cannoball Adderly record. Do 45's require higher anti skate setting or is just a peculiarity of this record. The vinyl system is an LP12, Arkiv B and Ekos II, which invariably tracks very well.

Skating forces are a function of the rotation of the LP and the tracking error of the arm/cartridge. So if you increase the speed of the rotation, there will be more energy (skating force).

I am with Doak in that skating force originates due to friction between the stylus tip and the groove. That friction force is a constant with respect to velocity (but not constant with respect to much else). Nevertheless, the only difference between a 45 and a 33 would be groove modulation. Now I think of it, 45s may be cut differently; the music has more "room" so the groove walls may be less tortuous. Ergo, in certain cases and for certain musical moments, I could imagine there could be less skating force generated by 45s than by 33s, but only for that reason. For example, this might apply if you listen to exactly the same musical piece on a 45 vs on a 33. You found that an increase in anti-skate cured your problem, which would not be consistent with my ruminations.

All of that aside, and assuming the 45 is made from the same vinyl as a comparable 33 (so that friction force is comparable), then skating force should be about the same.
