I experienced poi shift during a match end and it corellated with temp change. Initially I suspected scope shift but test results showed it was fps shift between 78f and 95f. Tried to re- create and measure consistency with tuning, turned out tuning reg from 90b to 110b while keeping fps centered around 905 with hs adjust the shift remains below 15 fps. Equipment = fx dreamline .177 with jsb 10.3g pellets. Happy for now and wanted to share
