Using Test LP - curious observations


I've been tremendously enjoying my Lyra Delos with the Classic for about 1.5 yrs now, and just recently remembered I had the Hi-Fi News Analogue Test LP and got the urge to test my setup.
Here are some of my observations that came as a surprise to me:
1) Anti-skate (Bands 6,7,8,9 on side one) - the cartridge "passed" the test on Band 6 without any anti-skate, but there was audible buzzing coming from the right channel at higher amplitudes. Applying anti-skate made NO difference whatsoever to the results, whether on setting 1, 2 or 3 (most anti-skate). I prefer the sound without anti-skate so this only seemed to confirm that applying anti-skate arguably does nothing to improve the sound and likely makes it worse. It also seems to shed some light on why Harry doesn't like anti-skate.
2) Azimuth (Band 5 on side two) - My preamp has a mono switch so this seemed pretty straightforward. According to the instructions, there should be minimal (if any) mono output if the cartridge was aligned perfectly. Well, there was certainly some output, which immediately worried me, but what really left me scratching my head was the fact that no adjustment appeared to correct it, or make a significant difference. I use the Soundsmith's Counter Intuitive to fine-adjust VTF and azimuth, and after about 2 hours of a wide range of adjustments in azimuth through the CI, it was virtually impossible to determine the optimal azimuth setting, i.e., the output seemed consistently the same regardless of adjustments.

Please free to comment, share your experiences or explain my curious results. Or are they not curious?

The anti-skate bands are notoriously misleading. Everything I've read says if you get no distortion on level 6, then go no further with the test. You'll only screw things up by trying to eliminate the buzzing on the higher level tracks.
Same experience with (1). The only arm/cart I own that would pass the HiFi News "torture tests" without buzzing is an ancient Empire 98 tonearm with no anti-skating provisions. The cart was a Stanton 881. VTF was 1.5g.
I use the same HIFI News 'torture test' but with the assumption that they (may) provide some indication about the stylus condition (?). To my knowledge 50 micron should be adequate for any 'normal'LP. My Phase Tech P-3G 'refuses' to
pass the 60 micron test but will pass any 'normal' LP test. The most
of my MM carts pass 80 micron test with 1,5 g VTF but there is a correlation with the anti-skate. With more anti-skate force the 'buzz' from the R.channel disappear. The logic suggest that the 'buzz' means more pressure on the 'outside' (R.channel) groove but above, say, 60 micron the question may be only academic(?).

Regards,
Keep in mind that the channel balance of phono cartridges is in the 1-2 dB range. So you are bound to hear something on the mono test. I think the intent is to find the minimum level which should be at the optimum geometry point. I perceive just the slightest shift in soundstage center, like maybe an inch, when playing records vs. CDs. I'm assuming it is the difference in channel balance of my cartridge and maybe even compounded just a bit by the preamp tubes.
