Compliance @ 10Hz Micro Acoustics MA3002

I need to know the dynamic compliance at 10 Hz?

I measured the FS mounted in Grace Teak G-714 tonearm, I'm not sure of the effective mass of the tonearm I read 6 gr on the net but I don't know if it's correct so I'm really lost. The FS measured is 9 Hz using the disc test Hi-Fi News Analog Test LP.

After the measuring I'm more confused:confused: or the cartridge have a really high compliance or the tonearm have more effective mass.
