If you're talking about groups, anything over a few bars screws up my groups from 100y and beyond. I was trying to eliminate variables a few weeks ago while trying to reduce spread / deviation, and I was filming my regulator manometer while target shooting across both my Caldwell and LabRadar. I was using 27gr NSA slugs for the test, and all the slugs were identical in side weight and shape. I also wanted to see how fast or slow the reg took to depressurize between shots, and filming this was harder than you'd think (part of the reason I bought a small shooting vise).

While I cannot be certain about the variation of force in my spring and hammer, the one metric that was consistent with velocity drops (and bumps) affecting the accuracy of my groups was reg pressure.
