I don't mean that current trends are evidence against it. I mean the physics is against it being any different from dolphin kick anywhere but right at the surface. The rest of my argument was why dolphin kick isn't faster than freestyle. Then the question is why don't they just stay within a foot of the surface? The problem is buoyancy. You have to be able to control your depth to keep from surfacing before you want to. It's hard to do that so close to the surface.
