OK this sounds like a stupid question but someone at the pool told me that my hand needs to be open with my fingers apart when I swim. i normally cup it which is what I thought was the best way. Today I tried my fingers together and my thumb out a little bit from the hand.
The cupped hand seemed best but what do the experts say?

As a thought experiment one can image a paddleboat with paddle wheels moving at a constant velocity. The boat can move forward without requiring the paddles to accelerate. The question is how much of the propulsion is due to the paddles accelerating water backward and how much is due to the drag on the paddles as they move backward.
I have tried that experiment after wipeing the bottom of a model paddle wheel boat with camphorated oil, with the paddles removed, you woud be amazed how far it went with a push. Camphorated oil breaks down the tension.
