Well, I was in a hurry and I screwed this test up a bit. I forgot to bring my camera and my BB gun so I didn't produce a video or get a calibration figure immediately before testing. I did calibrate it at home a few days before the test but technically it's supposed to be done immediately before the test. I still thought it would be worth sharing the results. I'll repeat the JSP test and do it properly since I wanted to see the JSP from a carbine anyway.
