Um, sorta. Yes, it is related but not 1:1. The gauge shows psi in the cylinder. That is NOT pounds tension or pull on the backstay. You need to take into account the pressure area of the piston. The pressure area of the piston on a Navtec 10 series is 1.160 square inches. (Pressure area is the area of the piston minus the area of the 0.5 inch diameter rod).

A decent rule of thumb would be 1.2 times gauge psi = pounds pull for a NavTec 10. I still find a batten with colored tape to be easier. https://drive.google.com/file/d/15VQF_A2X3ZNBW5ZPueAaJ9mw23X8YsQH/view?usp=sharing -- Dennis C.
