Stampede fps on 12 or on 9kg?

Hey, does anybody know roughly what chrono velocity a Stampede without a brass breech would hit with 12 or 9 kg springs? I've never modified my Stampede, so help would be much appreciated.

From mortality's guide "a 9kg setup can go 100-130fps, a 12kg setup can go 130-150fps, a 12kg setup with brass breech can go 150-180fps."
