The accepted value is 9 to 11 percent of VTF at the start of the record decreasing slightly towards the center. The biggest variable is velocity (modulation.) The higher the velocity the higher the friction. You can only shoot for an average value.
Millercarbon is prone to extremes, "varies tremendously across the record." This makes him difficult to believe. 9 to 11 % is not tremendous.
Lewm, anti skate can be adjusted to an extent during play. The geometry of many antiskating devises automatically lowers the anti skating force slightly as the arm traverses toward the center. I used the same method by listening. It takes some fiddling to get it right. This method puts you where you want to be easily while setting up the arm. Psychologically it is nice to work to a number. But whatever. The main point is that you can do exactly what the Wallyskater does without spending $250. It is a product without a market. Rube Goldberg could not have done better.
