Mechans, no argument taken!
An arm will track a cartridge well if it and the cartridge together have an effective mass that allows the two to have a low frequency mechanical resonance between about 7-12Hz. If the mechanical resonance falls outside of this range you can have all sorts of mistracking problems.
Additional factors are the 'sticktion' of the arm bearings, any play that the bearings might have, and uncontrolled resonances in the arm tube that might cause the arm to editorialize.
In addition arm bearings can be fragile! This can result in really variable results. But if all these factors come together in a good way then the arm does not have to be particularly expensive and things will work fine. If OTOH something is a little off the results can be dreadful.
Sounds like things are working better for you than bad :)
Have a good holiday!
