Pretty good for having been swamped, Ivan! Here I am just retired and I can't do exercise 20 as fast as you!
It looks as though you're doing well using the rest strokes, something I'm still struggling with, as I can only use them decently at a too-slow tempo.
Hi Paul - thanks for reviewing my videos. I would say that I am clearly no teacher or expert (otherwise I wouldn't be in D01
) but my advice is to keep working on that rest stroke and it will improve. By the nature of the movement, rest strokes are unavoidably slower than free strokes, but they provide a different sound and volume than free strokes, so it's a way to add dynamics and change things up. These exercises are meant for us to specifically use & practice rest strokes, but I think when you are playing real music and have the choice of how to play a piece, you will simply use them when you can, e.g. when the music tempo is slow enough or seems to need extra volume punch.
I recently bought "Solo Guitar PLaying Vol.1" by Frederick Noad (definitely recommend it) because I read that it's one of the most definitive classical guitar books ever written... and in Lesson 1 Noad teaches the rest stroke and states that "probably the greatest difference between the professional and the amateur player lies in the use and handling of the rest stroke
". So I'd say keep working on it. It will never be as fast as a free stroke - but it doesn't have to be.
