Anti-skating question

I recently installed a new phono cartridge (DynaVector 10x4 MkII on Origin Live modified Rega RB250 on Planar 3 table). At first, I set the anti-skating force so that on a spinning grooveless record surface the tonearm would pretty much stay where it was set down or drift slowly outward. That, I assumed, was a pretty good and direct way to set the level of anti-skating force needed. Then, I put on HiFiNews&RecordReview’s test LP and used the anti-skating tracks – basically, you adjust the anti-skating until you hear no tracking distortion of the test signal in either channel. This procedure gave me a very different setting – one that does not counter (not nearly totally, anyway) the inward skating of the tonearm when set on a grooveless record surface. I would have thought the two methods would have produced more similar results. Any explanation for this? (I’ve stuck with the sonically-based setting for now.)

My puzzlement is that I’ve had to set anti-skating to less than what I’d expected, not more. To illustrate: Tracking force is 1.9 grams, at the high end of manufacturer’s suggested range. Using the visual, grooveless record method, I set anti-skating to a certain level. When I put on the test record (has four tracks with signal stepped up in amplitude to gauge anti-skating), this setting results in the left channel starting to mistrack before right channel, and I have to reduce anti-skating to achieve balanced L-R tracking. This is the opposite of what I would have expected. ………. Well, this really is mostly just intellectual curiousity. With so many geometric factors at work, it’s a puzzle. The setup is checking out OK according to the test record (with possible exception of azimuth, which may need fine-tuning of such a small degree that it might drive me crazy to attempt on a Rega arm), and the setup is sounding fine and balanced when playing real music. I’ll just continue to listen as the cartridge breaks in. If anyone wants to comment further, I’ll read with interest.
