@drbond , The calculator is a rough guide as cartridge compliance can vary even with the best manufacturers. You tune the tonearm and cartridge with a test record by adding mass to the head shell. Starting out with a tonearm on the light side is always the best thing to do then you add mass till you get the lateral resonance down between 8 and 10 Hz. There are many types of head shell weights available. Soundsmith makes a very nice set of graded cartridge screws that work great with SME arms.
@edgewear , The Anna Diamond's achilles heal is that it is very low compliance which means you have to use a more massive arm and tolerate accelerated record wear. The vinyl has to do more work to move the stylus. But, it's motor is excellent. Very few cartridges can attain the low distortion levels of the Anna Diamond. The Verismo is the culmination of all this research. It is a more compliant cartridge with an ultra low resonance body and the low distortion levels of the Anna. The price is also a bit more realistic. To my mind only Lyra and MSL make cartridges as sophisticated.
