Thank you for posting those pix and I agree with Buconero117. Everything you've tried or could try with this cartridge is a waste of time and discussions of anti-skating (or whatever) are beside the point. The cartridge's cantilever and generator are obviously, visibly and significatly misaligned. No amount of user adjustment will make this cartridge perform as designed.
If this is a new cartridge bought from a Clearaudio authorized dealer, it is unacceptable and should be replaced under the warranty. Do not accept their lame explanation, insist on your right to a defect-free product.
If you bought used or from an unauthorized seller, the phrase 'caveat emptor' would apply, though perhaps only in retrospect. ;-)
P.S. and FWIW: You're correct that excessive anti-skating would cause L channel distortion, while insufficient anti-skating would cause R channel distortion (assuming anti-skating was involved at all, which I doubt in this case).
That said, etbaby and Lewm are correct that using a blank disk to adjust anti-skating (or any other parameter) is only of value if you're going to play blank disks. If your goal is to play music, setup must be optimized with the stylus in a spinning groove playing music (not test tracks). That's the condition you're trying to optimize for, that's the condition to use. Toss the test records in the dumpster (besides, you're mis-interpreting the 4 anti-bias bands at the end of side one, as most everyone does).
