Well, I'm not going to argue with someone with 16 times more coaching experience than myself ...
... much ...
... but I think the difference in our interpretations is mostly due to our disparate opinions of how far we think a vaulter can deviate from pure Petrov without becoming non-Petrov. And I'll automatically take your opinion on this over mine, since you've STUDIED Petrov so much more ... I just VAULTED that way.
In Starkey's case, I didn't like the way he carried the pole either. Just as you say, his top arm was too far back, and it seemed to cause some balance problems in his run and plant.
As I mentioned, I thought (and still think) that the key differentiator between Petrov and non-Petrov is whether the vaulter passes thru the "flat back" position quickly (or not), and whether they tuck (or not) there. In both Starkey and Stevenson's vaults, I didn't see that. I'll have to take a closer look, as I accept your definition of the Petrov Model more than my own.
To me, Starkey's pole carry flaws don't mean that he's not following Petrov. They just mean that he's not that perfect in his Petrov technique.
I'm also happy to agree to disagree re Stevenson's lead knee drive. You say tomatoe, I say tomAto. No problem. I'll have to take a closer look, to see if he's killing his swing, or if he's penetrating better by moving his CoM closer to the bar. I thought the latter, but have yet to look at any slo-mo. I'm more wondering if he's pushing with his bottom arm or not ... and to me ... that's the killer. If he's pushing (blocking at all), it's not Petrov.
STILL not answering Jam's question, but I'll put it a different way ...
Can anyone name (and show vid) of an American elite vaulter (5.80+, let's say ... or heck, maybe even 5.60+ or 5.70+) that's closer to the Petrov Model than Starkey or Stevenson?
Brian? Who else?
