In an electro there is this little thing called dwell. This is the time lapse where the board resets waiting for the next trigger pull. In a pneumag there is no board to help you with lazy fingers. Short stroking is most likely happening due to your fingers overlappping, not allowing the ram to travel back completely to rest postion. To verify this pull as fast as you can with one finger only. If you are short stroking then it could be your valve, the LPR or not enough clearance between the sear and the ram. This may keep the on/off and sear from re-setting. If the gun fires as fast as you pull the trigger with one finger then it is you. Walking a pneumag is someting that needs to be learned and practiced. Some can do it and some can't.
When setting the ram position on a pneumag I usaully leave 1/8" to 3/16" gap between the ram and the sear. This is to similuate or create dwell.
I also believe the problem that most are experiencing with the Cheater is exactly this. Zap sets these with almost zero clearance between the ram and the sear. I am also concerned about the plastic ram. Mag valves are relatively hard on things and I feel that the plastic ram will be the weak link in the Cheater. Only time will tell though.
