I think this is a good thing to have.... A lot of people don't enjoy reading a paragraph of text describing something with only pictures. Although somethings can be summed up very easily in how to do others cannot so maybe instead of trying within that one black scene between clips you could just link the thread describing how it is preformed to SinkingHigher Guide.
Better yet why not just do multiple videos for each one of sheik techs and special traits...Heck you could even go into combos as well such as the dtilt, dtilt, ftilt ~lock, Decay ftilt into Usmash, jab jab, dash grab(I think you already had that one) fair, ftilt, and so on..
You could also show killing %'s for characters as well from the usmash. Although my thread listing them isn't the lowest it can kill (it's roughly 6% less then what I listed) you could easily still use that data.
edit: Talk to me if you need to find a use for anything in a useful way other then needle pulling and chain jack. Beside those two I use everything that is Sheik. You know what, just talk to me. I'll pitch ideas at you. I've been wanting to make a sheik video since my "More ^B information" thread.
