This last reply beat me to it. Most VPI tone arms allow VTA adjustment on the fly. And decades ago Technics produced some gorgeous tone arms with infinitely adjustable VTA that felt like adjusting a lens on a fine camera.
Most of us adjust VTA for best sound so it doesn't ultimately matter in this case what SRA is.
By the way always adjust vertical tracking force 1st. Changing VTF will also change VTA. In fact if your arm doesn't have fine vertical djustment you can use VTF adjustment for fine tuning VTA if your arm permits fine tuning VTF. First set up the hight of the arm for a VTA that sounds good after setting the VTF in the middle of the recommended range. Then very slight adjustments up and down of VTF are also fine VTA adjustments that should have no significant affect on cartridge tracking.
