I have been studying videos of swimmers and find what was once called the "S" stroke has almost disappeard.
I have noticed that flyers use it. But crawl swimmers have modified it so much that it is almost gone.
Has it been replaced completely or was it an optical illusion? Did underwater film show us it did not exist.
In other simple terms..you can't really apply hydro-dynamics of rigid structures to those of human motion.
Example 2 – Take that Mississippi paddle boat, extend the paddle 1/3 again in front of the boat, teach it proper EVP (Early Vertical Paddle) and have it pull/push the paddle past amidships ...and it's a different story.
Sculling the hand at 14,000 RPM provides the same effect as does a propeller, but it may cause other problems.
