5 hours and 10 minutes is basically half an hour different from 4 hours and 38 minutes. First he says the time on the hangar video is off by 5:10, but then he also says he found it was 4;38.. so which is it? I'm not asking about the 10 minute drift during a year in a closet.
The time when it was actually connected was off by 4hrs 38minutes. It drifted in the closet for a year to being 5hr 10minutes off. It drifted another 10 minutes to 5hrs 20minutes while sitting idle and unconnected from the time the video expert first saw it until the time it was analysed.
