My 2 cents. The Shelter's VTF requirment, like most cartridges, is temperature dependent. My 90X is mounted in an OL Illustrious arm and for ambient temps in the range of 68-70f I track at 1.99g. Higher temps require less tracking force. I use a trick I gleaned from Doug Deacon and use different weight o-rings slipped on the arm stubb behind the counter weight. The temerature lets me know which o-ring to use and I can repeatably fine tune the tracking force with out having to move the counterweight and measure the VTF.
