Human error still is a factor in statistical error, as is possible slight, albeit unnoticed, lags in streaming or CPU processing (especially when using the laptop vs. the desktop). Also, the length of the skateboard and hoverboard does not allow the IF to get as close to the wall when starting or stopping as compared to just wearing a costume. I realize there are many variables, some of which could be compensated for, when performing these trials. I am just saying that if all could be taken into account I believe there would be little significant differences in the quickness of IF's no matter what costume or vehicle was being used, or none for that fact. As far as the control of the stopwatch, I tried my best to hit the button as soon as I hit the arrow key to begin moving and as soon as the IF or vehicle hit the wall. If the timing was off I ran the trial a second, and once a third, time. I think +- 0.3 would be acceptable, especially considering the quickest I could start and then stop the stopwatch was 0.12 seconds
But we could get into all kinds of statistical debate, and everyone knows statistics can be manipulated in ways to make it appear that outcomes are favorable to whoever runs the data (having worked in the nuclear field it was always entertaining to see the anti-nukes and pro-nukes spew out statistics, using the same data population, supporting the dangers or safeness of nuke plants). What I was trying to show was that there is very little difference in the quickness associated with different vehicles or costume. If anyone believes any particular costume or vehicle is quicker then go with it.
