With unfeathered blades, your two hands have a paddling motion

mostly stationary with respect to the paddle. Upper-arm movement
substitutes for a certain amount (10cm?) of paddle length

I don't see why you have this difference. I use the same technique
(closest to your second description) whether feathered or not.

The former technique is what I tell folks to stop doing and the latter
is what they should do.
