Dear Nil: In all those links that other people posted you have almost the answer for your questions.
+++++ " What kind of tolerance on this right amount is tolerable without loosing too much of a signal and ... " +++++
The tolerance range ( up/down ) is the one that the manufacturer gives at the cartridge operation manual. Between that range you could " move " but you have to take in count all the others parameters that has relation with the VTF for stay right on target: """ I do some clue that the amount of signal that cartridge retrieves from grooves is miniscule...""""""
The next step and a very critical an important one is that that minuscule signal could be amplified with enough gain and with out distortion/noise/colorations an according to the RIAA eq. and that's means with a RIAA deviation no more than 0.05 db
Regards and enjoy the music.
