None that I am aware of. It's a short enough run that your best bet is just to watch some of the top times.

I tried to record a tutorial one time -- just took one take of a recording. Wasn't satisfied with how that draft turned out, so I never posted it, and didn't continue work on it either.

If you see anything in the runs you watch that you don't understand, feel free to ask about it here, and I can try to explain what's going on or how something is done so quickly.
