1) This would then also be the case with tangential tracking arms, but it isn't.
2) There is a skating force present on a grooveless record too, so the groove is not solely responsible for the skating force.
The skating force on a grooveless record is different from a record with grooves, but the difference is not huge. I have tested this, using a grooveless record and a test record with anti-skating test tones. The results were very close, and both were very close to the recommended setting of the turntable.
I always suggest using the method outlined in the user manual, and forget about it.
