How to change effective mass of a SME V.

I have a SME V. Its effective mass is quoted as 10-11. I wish to alter this to around 15-16. If I add mass to the headshell (and know how much) and crank the counterweight back how can I accurately re-calculate the ffective mass? The cartridge is 9.1 Gm, compliance 6. I know that the arm resonant frequency will change as well.

Holly mo!
Nick this sound very involved indeed.
I think a reasonable and quick approximation is to take off the counterweight and cart, then place the arm on a micro-scale. I did this with a 9c (Pro-Ject) arm and is was the exact weight (mass) as stated it should have been, 11g.

Go figure,
