This may be controversial but is SDK really mandatory for fast freestyle?
Don't see much of it here, it looks like they wan't to surface ASAP:

I know proponents will link to Phelps' 200 WR, but other than that, I don't see many people exploiting it.
Will we see huge SDK in freestyle at the upcoming Olympics?
I don't fly because of my back, so my SDK in freestyle is minimal. I'd like to think I don't need it.
I'm keen to watch for it in elite freestyle races and it is a mixed bag. Many are fast without a big prolonged SDK.
if you watch crocker's turn / SDK at world's in the 100 fl
there's not much glide after his push off
he begins his SDK almost immediately
there's a little more glide off the start
A submerged dolphin kick done prematurely detracts from a streamlined position and must be done only when forward momentum is slower than the speed generated by the kick itself. The Hillmen Swimming Start Comparison Chart will allow you to objectively measure your "breakout" efficiency.
A SDK is often done prematurely after a push-off from the wall. And let's not forget, swimmers with terrible kicks must come up more quickly then those with better kicks. It is also important to objectivey evaluate turn times (breakouts) to evaluate which kick is the best and the proper distance to kick.
