If elites would swim with more kayak timing and with their head out of the water, it would still look exactly as Tarzans stroke.
Because he has to trash his arms in the water and push down more in combination with a more kayaklike armtiming, there is more disturbance on his balance, especially from the arm entry on the 3th kick(arm entry on one side/arm exit on other side), which is more powerfull and starts to look as the main kick almost, but otherwise the resemblence with Thorpes kick is striking.
He even has the same 2 stage depth from first- inbetween- third in his kick action.
These guys must have an instinct that hates a leg that sticks out too far in the underlying stream of water and creates lots of drag.
Tarzans postion is angled down more than Thorpes but its not that bad.

Does this all mean we ought to strive for a slight upward curl to the body when trying to go a bit faster (without allowing the belly to sag - that would cause extra drag for some of us! )???
You dont want a hollow lower back though, so most of the posture change happens in the upperback. flat lowerback, legs up by flexible hip flexors.
Better for freedom of shoulder movement also, but if you are used to a rounded back. a straight back feels unnnatural and takes effort to sustain.
Swim posture and computer posture are opposites.
