Test records will not help you set antiskate, except for playing test records. You're already using the correct method, listening to the records you actually play.
Stringreen's suggestion that you may be hearing permanent groove damage is a good possibiliity. Test for that before going nuts about A/S. Here's how. "Play" a passage with a noisy R channel by spinning the platter by hand, v-e-r-y s-l-o-w-l-y. The music will be a very LF growl but groove damage, if any, will be much sharper and crisper. There's no way you could confuse it with music, because the transients from groove damage are much faster and sharper than any music cut into a record.
If these noisy records are NOT damaged, try increasing A/S in tiny steps as you replay a noisy passage. It's BARELY possible your VTF is set right on the edge of mistracking, in which case A/S might prevent it. When you have enough A/S to balance the noise in both channels, you have enough A/S.
For checking VTF you need a balance or scale. No test record, just a scale to find out where it is and your ears listening to real music to decide where it should be.
You have good instincts, keep workiing and the sound will get better.
