Let’s look at double-escaped wrist-only strokes, and let’s look at a downstroke, say 9-0-2 (the clock face model, where 0 is in the middle). The stroke STARTS at 9 with deviation, and then when the pick is going towards 0 the stroke STARTS with extension (going up), and it will end up at 2, and then, in parallel, both motions STOP. So, look at it in time: there is a START (deviation), a delay, a START (extension), and then two STOPs. (Note that both cannot start at once because otherwise a line would result, and not a curve.) Now, I think the problem comes up going backwards.
My first question: Does going backwards go from 2-0-9? If so, I believe it’s a string-hopping movement, in the sense that both would START, and one (flexion) would STOP around the 0 in order for the pick to return to 9. (Unless one turns the forearm to reorient the hand, but I don’t think this is going on.)
Going forwards isn’t so bad because the stopping can be sloppy (the pick is above the string plane), but going back 2-0-9 seems precarious.
Is there something that I am missing?
