I spotted this during another search and decided to give it a shot. I found the experience useful. Although the sound was excellent when "loosely set", I found that barely "nipping" the screw up by 1 degree was slightly better - not a massive improvement - which was probably close to the setting I had when I initially set azimuth for this cartridge. That might also confer a wee bit of damping too.
I've a feeling that it may well turn out to be a "fine azimuth adjuster" (and perhaps a fine damping adjuster) - at least between the limits of being loose and tight. I've now considered noting the angle of the lock screw's Allen key e.g. in the manner of the hand on a clock face, whenever altering VTA so that I can fairly precisely replicate the setting.
A useful experiment so thanks to the OP for that. ;)
