"Does anyone else do this giving verbal feedback about your body thing or is it just me?"
All the time! I find it really useful as a rule, either if I give this feedback to my nage, or my uke gives it to me. Sometimes the difference between getting the leverage right and wrong can be too small to see easily, so that kind of verbal feedback is great. Especially if the nage is aiming for some kind of lock, when you get: 'Not quite, not quite....twist a little more clockwise....bring the elbow a little higher....a bit more....YES![taptaptap]'
