Did everyone miss Ace's post? A tripod is such a simple solution to this problem! I can set my tripod up at a height anywhere between ~2' to ~5' including the ability to change the vertical angle of the camera. No akwardness of asking someone to tape, no wobbly image from someone's shaky hands, and no need to carry a stack of books to the court and fuss with getting the correct angle.
Regarding taping a stroke vs taping a match, I think both are helpful. Taping a match gives you a good opportunity to analyze your shot selection, strategy, and footwork but given the wide image angle you need to get the entire court, it's hard to focus in on the technical characteristics of a stroke. I find it easier to analyze technique if I have a controlled situation where I'm hitting balls from the same spot so that I can have the camera zoomed in closer. But I guess it would also be valuable to see how technique holds up under match pressure.
