That's pretty much the technique I was describing, albeit with a somewhat loose execution.
Yah I wasn't looking for quality, just an example of what I thought you were describing. FWIW I don't recall ever practicing this technique as a technique apart from the randori exercise. Why that is, I can't exactly say, though my thoughts are that it's a matter of practicality or maybe the very specific attack requirements to be practical. With that said, this is one of the two techniques I've done on someone in a real situation and it was quite effective. Though maybe that says the technique as part of the exercise is more important than the technique alone. Worth noodling on I suppose.
