Cartridge Tonearm compatibility

Hi,
I need some help calculating cartridge/tonearm compatibility. I am considering building a DIY turntable. I have purchased a Maglev table and a Jasmin motor from China on ebay. I am currently building a custom plinch and arm-board.I have purchased a Jelco SA750E tonearm. I am considering a Dynavector XX2MKII cartridge. I have looked at resonant frequency calculators but quite frankly they are above my knowladge. Would the Dynavector XX2MKII be a good match for the Jelco SA750E. The tonearm mass is 13.26gr. The cartridge weight is 8.9 gr and the cartridge compliance is 10 mm/N.

This makes it easy if you have the arm effective mass and the cartridge compliance at 10Hz
https://www.vinylengine.com/cartridge_resonance_evaluator.phpIf you only have compliance at 100Hx multiplty that by 1.7 and you'll be close enough or halve static compliance if that's what you know.

Gary, forget about the math. Get a Hi Fi News test record and see what the actual resonance frequency is. I suspect you might have to add a little weight to the head shell. So, you add weight until you get the actual resonance frequency below 10 but above 8 Hz both vertically and horizontally.

Gary, you can read this thread first, maybe you don’t have to worry about.
Jelco is a mid mass arm and Dyna is a mid compliance (17cu @ 10Hz) cartridge. It should be fine!
In my opinion online calculation is always wrong, you can do that with Hi-Fi Test LP
