About the only field more sophisticated than political science is momentum transfer.
For example, on short sprints a simian armed ectomorph w/o a great lung capacity is going to benefit by diverting more effort to lift to hydroplane.
Women may want to get more propulsion from kicking.
Depending on the situation and what you are trying to do you should have dozens of different swimming styles.
If I look over and see a lot of two phase refraction of the light, either bubbles or splash, I know the other swimmer is moving stuff that doesn't need to be moved. He'll beat himself to death. As any hurricane surfer will tell you, if you cannot out macho the ocean.
Your swimming philosophy should be as minimalist as Strunk & White prose.
Never move _anything_ that doesn't need to be moved.
