Do you use video analysis in your table tennis training?

I use Kinovea video analysis tool for coaching with some of my students - it's very good for slow-mo analysis and comparisons, drawing on the video etc. Runs on android and windows, which is handy too.

There was an interesting product called R-deX:tt for match tracking that I was sent a demo of a few years ago, it was basically an A4 sheet of paper divided up into 3 parts: Scoring sequence (to track who was winning points on their serves/receives), How the points are decided - tracking whether points were won on serve/receive/3rdball/4th/rally - and The Winning shot - to track what type of shot won the point, where it was located, where it was played from. I think the company must have gone out of production since I can't find any mention of it on the internet. When I get back home tonight I might try to dig it out, scan a page and show you what it looks like, I don't think anyone would mind at this point.

I never used it really but the creators claimed that with practice it would only take a couple of seconds to tick the various boxes after each point, to allow you to get a good analysis of the patterns occurring in a match.
