record weight .... correct weight?


Searching in the web, there is a wide range of weights for what we put on top of our records, goes from as low as 200grs to 3 pounds .... why those differences? is 3 pounds really necessary?,what should be the correct weight for this devices and why?, I would like to know your ideas about this matter.
thanks in advance

Elinor mentions: " Also take note of the number of exhibitors at shows no longer using weights or clamps at all." and that's really interesting, maybe there is a reason for that
Could be a matter of convenience(?) but if their gear was sonically disadvantaged by not using clamps & weights you'd think they'd want it to be fully "tricked up" to impress the punters...?
Exhibitors at shows may be more concerned about someone dropping a record weight on the turntable than trying to get the absolute best performance out of a compromised room setting. Electronics shows are not where published reviews are conducted.

An expensive cartridge could easily get damaged or the beautiful finish on a plinth or tonearm could end up with a dent or scratch. The nuanced sonic gains of a weight or clamp may not be worth the risk. Unless a turntable designer/ manufacturer (or similarly knowledgable vinylphile) speaks up, we won't know for sure.

Just sayin'...
You do realise you've just panicked half of the weight-wielding Audiophiles out there :)

You've got them sweating over the ongoing health of their Goldfingers and A95s...especially if the Wife has just used moisturising lotion.. ;^) :)
