Superior Gun Works Load Dev Page

New reloader here. Looking at the load dev on here and it measures the jump in degrees. I thought that was a measurement in thousands of inches. Can someone explain that to me. Thanks

The 6.5 prc +p Loads with 156 bergers are really slow. What gives? They are same speeds as the non +p .
