You should know that the ;xx is counting the frames and not counting milliseconds. You can notice because it goes 29 and then back to 00. To convert 14 frames into milliseconds, we need to know HOW it converts. 1 frame with 30fps timing (the timing shown in the video) is equivalent to 0.033333... seconds. Using this, we know 3 frames is 0.1, and now we know 15 frames is 0.5. We take off a frame and get 0.466666... which now means the proper time for the 20 second run is not 20.14, but 20.466.

It's not making much difference, I don't see anybody else getting that lucky...
