With an 11.5gram effective mass tonearm, I get around 10Hz as your calculated resonant frequency in the horizontal plane, and 11.2Hz in the vertical plane, using your listed formula. 10Hz horizontal and 11Hz vertical is just fine. The actual measured frequency on your turntable may vary some from the predicted, but it should be fairly close.
The OL Silver MkII is about 11.5 grams
You may note that the cm/dyne rating is also known as compliance units(cu).
As you can see, this is a combination of a medium-high tonearm effective mass(11.5g-the higher end of medium), and a medium-low cartridge compliance(with 12vert. being in the lower end of medium compliance, and 15horiz. being in the medium). It fits nicely into the general categories that I presented in my earlier post.
However, with the light cartridge mass of 4.2 grams, the counterweight may have trouble achieving counterbalance, so the the supplied ZYX headshell weight may need to be used, and this will change the calculation, but even a 4g headshell weight increase will still yield results in the similar area of mass/resonance, and certainly still be in the target frequency range.
With a cartridge like the ZYX, you may choose from either a quality gimbal-bearing arm like the OL, or a quality unipivot tonearm with sufficient mass(around 11g).
