I didnt touch anything for settings, I had wanted to overlay my aim data but screwed that up, so I just overlayed whatever internal GPS data the gorpo had recorded. I was actually surprised the gorpo speed data was accurate, normally when I turn that thing on in my car before a session, it doesn't lock in correctly and speeds and stuff are all out of whack.Did you get that GoPro time by stopping at full seconds and advancing the start and finish one frame at a time? At 30 frames/second, that's 0.03 second resolution . . .
