The HFN record is a test record and as far as my understanding is concerned it is equally recorded on both sides of the groove.
Which means that you will have both channell perfeclty tracking only if the cantilever is perfectly laid and force-balanced in the groove.
What you are saying is interesting and all in all you set using the finest instrument you have i.e. your ear!!!
I don't see though how scoping a real record would be of any help in terms of A/S, VTA, VTF, Azimuth regulation.
