What defines a high compliance cartridge vs low


This question has two parts and derives from the recent tone arm thread.
What do you think is a highly complant cartridge specification? What would be a low or resistant compliance figure? Where does one draw the line in terms of the specs provided?
Knowing that tone arm mass and compliance are important considerations for optimal performance, then what formula, or ratio do you use for optimal tone arm mass for a given compliance? Or Vice Versa?

Stanwal- At what frequencies were those compliance readings taken? Everything changes DRAMATICALLY, when read at say, 100Hz as compared to 1k or 10kHz. Read the info available at the last site I recommended, as to compliance ratings. The REALLY important compliance reading, re: tonearm/cartridge resonance, should start at 10Hz.
Interesting figures above. FWIW; Anything under 10g is considered LOW MASS, and if a cartridge had a compliance of 50; it would be considered Stratospheric(high compliance STARTS at 20, and the charts only go to 50). I don't know about, "the Old Days", but none of the figures have changed since 1980. Here's a site that gives the formulas you need, and some pertinent info: ( http://www.gcaudio.com/resources/howtos/tonearmcartridge.html ) and another, that you may find useful: ( http://www.vinylengine.com/cartridge_database.php?m=Denon&t=mc&mod=103d&sort=1&Search=Search&sty=&ovlo=&ovhi=&can=&dclo=&dchi=&stid=&masslo=&masshi=¬es=&prlo=&prhi= ) Another point that many miss: Compliance varies with frequency.
