Okay, thank you for your thoughtful reply. There are still a lot of terms and movements that I don't understand in Argentine tango. Of course that is partially because I have not studied it enough. But it would be great to have some reference material that is a good overview of all the Maine terms, or a reference for a looking up something that I don't know what it is. And of course be able to describe what is done in English would be most helpful. But I know sometimes you just have to go do it and feel it for yourself.
This year I took classes at his son, Eric Dinzel. He's a good teacher and of course did not bother us with such a chart, although he followed the "Dinzel Method" somehow in the background.
(Sometimes he mubled terms like "on three" or "on five", but no other long term damages got obvious. )
I have used the Rasche notation as a tool when I have prepared for festival workshops. If I was going to participate on a sacada lesson I checked the last year's youtube videos for the teachers and run them with my partner as a pre class training. When I try to understand the steps and dynamic this notation system has helped me to stay focused and pay attention to every step on the video.
It is easy to write down Rasche notation on an ordinary keyboard and in some situations I use it.

I don't use it as a tool to save old step patterns because the videos and pictures are more detailed and available today but it has been a good help for focusing.
