Daystate New Daystate Delta Wolf, erratic velocity with advanced setting

Interesting and puzzling ... the suggestion about sorting might be worth a try ... or different , more consistent pellets. There were a few broken hammer return springs in one batch of rifles. It's worth looking at but unlikely. In my hands, I'd be going over everything to do with the hammer and solenoid connection... checking for loose or contaminated ... It should NOT take 15 shots to settle and if the reg is low enough, first shot out should be right on in Advanced mode ...
So inconsistent pellets or inconsistent hammer are about the only possibilities. The program itself in Advanced mode would be a HIGHLY unlikely source.
Factory mode is a different thing though. Odd that it's more consistent there...
