@lewm , whether you like it or not lewm the skating force increases with groove modulation which is synonymous with groove velocity. I have explained it as best I can to get it through your stubborn countenance. Maybe AJ Conti can do a better job. https://www.basisaudio.com/ajs-discussion-of-antiskate-forces/ You continually want to mistake groove velocity for linear speed. They are two very separate granted loosely related issues. There are only two coefficient of friction figures for any pair of materials, static and kinetic. The static coefficient of friction is related to the two materials in contact at rest which includes the "stiction" factor. The kinetic coefficient of friction is related to the two materials in motion which is the situation we are dealing with. The kinetic coefficient of friction does not change with linear velocity or what you would have playing a blank record, but it increases with increasing groove modulation which is synonymous with groove velocity. You object to the term groove velocity because it includes the word "velocity." When you see the term "groove velocity" just substitute groove modulation and I think you will be just fine. If not you can object until you are blue in the face but it won't get you anywhere except maybe a visit to the ER and I certainly do not want that so please do not stop breathing. We like having you around to argue with.
@nandric , while the skating force might change a tiny bit with stylus profile, other than the prescribed VTF the cartridge has nothing to do with the skating force.
