To my way of thinking, it sounds a little too arbitrary to say that certain vaulters are or aren't following the Petrov Model. This post is an attempt to ask for clarification.
First, let's clarify that it's the Petrov Model, not the Bubka Model. Isi is Petrov's latest instance of his model. So it follows then that if Isi does something different than Bubka, then that would merely be a style variant (or a flaw), rather than something non-Petrov, would it not?
And heaven forbid, if Bubka was to have a style or flaw that Petrov didn't agree with, would we say that he doesn't conform to the Petrov Model?
Who's to say that Isi isn't a "better" instance of the model than Bubka was?

And is there any tolerances permissable due to the physical characteristics of males vs. females? I haven't done this, but I'm betting that if we compare Bubka against Isi frame by frame, we'll find some differences that can presumably be called either style variants or flaws. Is anyone aware of any of these, or can we confidently say that Isi vaults "exactly" like Bubka? Or that they BOTH follow the Petrov Model "exactly"? She certainly does't fly off the top of the pole like he does. Is this just a matter of speed and strength, or is it more than that?
Now on to what constitutes a style difference or a flaw ...
I consider the characteristics of the Petrov Model to be:
1. The high pole carry.
2. The free takeoff.
3. Driving the chest forwards, without blocking out the bottom arm.
4. Long, powerful trail leg swing, with either a lead knee that's held up, or one that drops and then swings up with the trail leg.
5. No rockback or tuck. Instead, the upswing melds into the extension, without any hesitation as the hips rise above the shoulders.
6. The continuous chain, which covers all characteristics 1-5.
These 6 check-points may vary slightly depending on your interpretation, but I would think that you're not following the Petrov Model if you ignore any one of these.
Said a different way, I think if you qualify on 5 out of 6 of these, but aren't even TRYING to follow the 6th characteristic ... or aren't even CLOSE to doing it, then I would think that you're not "pure Petrov".
So how does Starkey score on this? I thought 6 out of 6. Unlike Altius, I don't see why an inferior pole carry or a less-than-perfect upswing or extension disqualifies him from being pure Petrov. To me, Starkey's pole carry is just a flaw.
Do the tolerances vary by "eliteness"? That is, if Liz Parnov's technique isn't quite as close to the Petrov Model as Starkey's do we cut her some slack because we KNOW that her father is STRIVING for her to follow the Petrov Model, even tho she's still unable to do it any better than Starkey?
Besides sex, does AGE matter? Or is the model age and sex agnostic?
Does it make a difference what Starkey's INTENT is? (I don't think it should. I think you should be able to identify the model by observing vid of a vault ... not by interviewing the athlete. He's either going thru the right motions or he's not.)
Altius, you can see that I have a lot of questions. I'm not expecting you to be the sole person to answer them, but since you co-wrote BTB2, and have spoken with Petrov perhaps more than any other English coach/author, I hope you'll chime in with your seasoned opinion ... as usual.
And I hope others will chime in with their opinions as well. I don't intend to get into a two-way debate with Altius over this. I just want to understand what constitues the Petrov Model and what doesn't. And yes, I've read the appropriate pages of BTB2 about styles and flaws, but I'm still confused.
