Compression Test-CYL Leak Down Results

I was preparing to do a valve lash check and as I reached for a tool I saw my cyl leak down Gage and thought that would only take a few moments. I put 80 psi in and was holding 72 to 74 psi . It was better than I expected, but I'm not sure if I should have had more psi applied. I tried 100 first and the crank rotated so i put it in gear and the bike moved. I couldn't lock the crank good enough so I dropped to 80. Has any one had similar results or what is the limit for a leak down.
