This was a great thought, but lacked some hard facts. First, when you start playing in the morning your marker is clean and lubed up nicely. After a few hours play your marker will get dirty and a lot of that oil will make its way off the bolt.
The LPR needs to be set in a way that will ensure that it has enough pressure to fire the bolt consistently every shot. You may be able to get away with the soft pillowy shots first time to the chrono, but if you try chrono'ing off after a full day of play you may notice very inconsistent shots.
Going back to my point, you can still tinker with your LPR to try and get that shot you had before, but I've found keeping the LPR at factory is the best way to keep the marker shooting consistently and in most every weather condition I come across.
Thanks brother I'll just put it at 1 turn out from all the way in then
