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 simple terms..you can't really apply physics on land towards hydro-dynamics.
I agree about mass and acceleration providing greater force...but the force has to applied effectively towards the water...not slipping through it.
Example...A Mississippi paddle boat with enormous horsepower moves huge volumes of water and goes nowhere fast.
Take the same vessel...replace the paddles with propellers...and it's a different story.
Sculling the hand provides the same effect as does a propeller.
It's the difference between slipping and gripping.
