I think you are doing something wrong , I put in for specs 64# 30% letoff, I believe this would be closer, 46 ATA brace height 9.75. I clicked off the release aid button because the way I took it you are shooting this bow with fingers. For the cams I put in there 2 cam soft. then the point weight and insert. Arrow length 30.5 , I wasnt sure what your draw length actually is so I put in there 30 inches . Anyway the 340's showed slightly heavy. Here is a snapshot of what OT2 showed.
