When ever I make trigger adjustments, I always use a scratch pad and make notes if which screw and how much it is turned..After some time is spent twisting and turning multiple screws, it is quite easy to forget and get messed up !! Each adjustment screw has a bearing on the others, so diligence is needed to keep things in order. Before starting...get out the paper and start making notes, just in case you need to backup an adustment. It does help !!!
