between +/- 1 and +/- 2 all day. went from 40 degrees in the morning to 74 in the afternoon. swapped barrels up .006 once.
AAANY ways. Check your spring setup. My valve spring caught on my back frame screw until I cut it down a bit.
if that's not it you might have some valve pressure issues. re-sweetspot and turn IVG in to desired, make sure to shoot 3-4 times in between every adjustment. that USUALLY fixes things.
Edit - check for obstructions in your valve air chamber, you might have a o-ring bouncing around in there blocking flow every couple shots.
