Very nice - your seconds are consistent...I've been doing it with an AR, so my average is 14seconds...but if you've done it twice with those results, the seconds should be right. It's suggested to calibrate at least 10times, lol...but since you're capturing, why don't you just do at least 2 more times - 3 to be safe to make it a nice 5? If you're too lazy to do this and just want to skip ahead, tell me :)
