Great forward planning. (I
assumed you were timestamping it, but had to ask...
) Recording the competition bit was a nice touch! (That's MUCH better than trying to sync the surge at power startup with the light on the robot coming on in the video!
)
Have you considered ways of now superimposing the data as an NTSC graphic over the contest video? Lots of advantages: Viewable anywhere, no special equipment or software needed, and you can freeze or slow mo the video in either direction without losing data sync.
Here's an example of a superimposed visualization: Create small, animated "color pie meters" in each of the four corners of the video to represent the four drive wheel currents. Three (or four) laps in different colors for Full Scale. This would be easy to interpret out of the corner of your eye, even if each were tiny.
I've included a sample: Three laps (Grn/Yel/Red), FS=50 Amps. Indication = 43.75 Amps = 5/8 on the Red lap (overwriting Yellow) = 21/24th of FS = 87.5% FS.
