A centimeter. So it is moving. Nobody says it has to move alot. We are just
overcoming a little drag, not trying to accelerate, so we don't expect 3
feet. I expect with a really efficient boat and very good technique, 1
millimeter or less would be all to expect. The bet was, would the paddle
move through the water, and the answer according to you is "yes, about 1
cm".

 I think the original idea that "...it is very much like having a long
series of posts set in concrete under the water" was probably not meant
literally by the coach. It is a visualization technique. Once you are up to
speed, the amount of motion in the water is small so "very much like..." is
pretty accurate. And if it helps you paddle better, go ahead and take it
literally.
