At your risk.
I am newbie.
A nice way to make sure (after or before using the cartridge alignment protractor?) the azimuth is correct is to remove mat and place a piece of mirror (without the plastic or glue!) on the platter. (Turntable should be checked to be level), It immediately reveals if cartridge is misaligned as far as azimuth is concerned. But what we need to have azimuth aligned is not the cartridge shell, nor the cartridge but the cantilever with the diamond.
But this is difficult to see in detail even with a magnifying glass.
So what was done?
A ridiculous low tracking face was set, for example 0.5g.
The record sounded awful but it sounded much worse if azimuth was out even a little.
The trick of unlocking the cartridge shell twisting a tiny bit (it natural foul play) then fastening it again made a difference. So it may be used as a way to set azimuth correctly?
Tracking force was then set by ear too. More than the optimum point and all easiness in sound, treble, bass is lost.
A bit like adjusting bias on a Pleiades BD139 class A single ended amplifier with loudspeaker DC coupled. If too many elements flow through the speaker cool DCwise, bass is out to lunch. It seems the resonant frequency is changing by increased stiffness in both examples? The sound becomes stiff.
Vicky immediately noticed after days of sound memory that something was clearly wrong when tracking force had been set by accident a bit higher.
And antiscating. It can make a difference in depth, easiness of bass.
VTA has not been auditioned too yet.
