Then why does the right hand not move away from the right shoulder? The right shoulder and right hand are moving in unison, and that doesn't happen in a throwing motion. I.e., if he were throwing at release, his hands would outrun the right shoulder. In MORAD terminology, it's a cp swing. Think of a hammer thrower - he pulls his hands inward against the pull of the weight on the chain and he's still pulling when he lets go. He can't throw because of the chain.

Because he is already rotating hard. If you throw ONLY, yeah the R elbow would straighten. But remember he tried to fire hose hips at Startdown, which really cranked up the rotation, and his L side extension allows that rotation to get even faster. Pure PA4. Then at Release/hands hip height, he starts thinking fire that R arm in sidearm/undermine throwing manner.

IMO, the more of what he did in BS, the RFT, the longer the R elbow would be bent and closer to the R hip.

Remember this is a very fast motion. The R elbow suddenly straighten starting visually right at Rekease/shaft parallel in DS. From thereon it straightens slowly as the DS is very fast. His R arm and R wrist is very very straight in followthru. Note also that his shoulders don't turn/rotate as much in finish like Immelman for example and Tiger circa 2000. So I'd say it's more PA1 for Hogan from shaft parallel, but he's also still rotating due to the earlier hip turn crank.
