Exactly!

"Aero rule 1- enough power fixes all other deficiencies"

Aero rule ?- MINIMUM DEFICIENCES require less power and allow the best economy of energy to fly a load from point A to point B in the same time.

Then, sailplane designers and pilots arrived to the concept of best Lift/Drag ratio, because the power of their machines is limited to what gravity can offer.

After that, golf ball designers and players engineered dimples in order to achieve MINIMUM DEFICIENCIES during the free flight of the balls, because the power of those balls is limited to what the muscles of the players can offer.

DEFICIENCIES: Anything that perturbates the molecules of air for anything else than what WE NEED them to do for us in a particular instant.
