resonance figure of 11 Hz, nearly ideal. are you sure about those figures?

According to the Cartridge DB my arm/combo should have a a resonace freq of 9 or 10hz. On the HFNTR it comes in at 15hz...If my arm truly has a mass of 11g (nottingham interpace arm) and the Karat weighs 5.3g and compliance of 15, something doesnt ring true.
I do love the sound, but if there is a warp on the record I do hear that energy coming out of my sunfire sub (xover is at 32hz) main speakers are Magnepan 3.6's
I have thought about getting a 3g headsheel weight from VPI to see if that would help.
Just have not gotten around to it.
I'll have one headshell fabricated from brass, the original isaluminum. I'll post my experience maybe next week.
If it were too high there would be too little bass energy all else being the same.

Hi Henry and Paul,
My turntable is Ambient, so its purely Clearaudio. When I subjectedit to Image Hifi Ultimnate pickup Test Record's tonearm-cartridge
resonance test, the tonearm started to shake from 16Hz to 12 Hz and
gave warbling sound. I was really disappointed since my other system
which consist of Cl A Emotion-Satisfy-Classic Wood passed the test
easily. And I'm sure the specs are correct.
Best regards,Joseph
