I posted this over on AT but haven't received anything helpful yet so I'll try here. I finally got around to putting the tape on my MBG Ascent Verdict 4 pin. The pins are set for 20, 30, 40 and 50 yards with the 50 being the slider. I've got the sight set up so "home" is in the middle of the slide (on the MBG the top of the slider rail is flush with the top of the fixed rail). This way I can dial up or down from 50 yards. When I dial the slider to 20 yards and shoot, the POI is about 2" lower than when I use the 20 yd pin with the slider at "home". Is this purely caused by a form issue (altering my anchor points) or is there something else going on?
