When I personally build gearboxes for myself I rarely short stroke anymore and leave gears alone, just have it well shimmed, aoe sorted and rof turned up or turned down on gate titan software. In rare occasion when i want to see how fast of and ROF I can reach that I short stroke gears. At the moment my vfc mcx gearbox is short stroked by 2 teeth on 13:1 gears and i get around 35rps.
