From a standing start simulates the PV better than from a kip.
Why would you say this? If anything sprinting towards the highbar, jumping to grab it, and then shooting to a handstand would be a better simulation.
As is often the case, disagreements or differences in opinion are dependent upon misunderstandings and different points-of-view. Such is the case here.
First off, after years and years of debating the topic of the "pull" and "push", we've still not establish exactly what we mean by each of these. And at this point, most of us aren't very hopeful that we'll ever reach consensus on the definitions of these terms. In fact, I still don't even know if Branko is referring to a pull or a push, because he used one of these terms in the title, and the other in the body of his initial post. So we could all be presenting our opinions based on misunderstandings.
Walrus, this is certainly true for your Point #2. I am simply saying that in the shoot-to-a-handstand highbar drill I was referring to, I explained 2 options (#1 - from a standing start, and #2 - from a kip). I did not mention a third option (sprinting towards the highbar). So when I say that OF THE TWO
OPTIONS, "from a standing start
" simulates a vault better than "from a kip
But now that you mention it, I have also done (and coached) this drill from a JOGGING start, but NEVER, EVER from a sprinting start - even though I concede that from a sprinting start MAY simulate a true PV better than the other 3 options.
I did not mention from a sprinting start because I think it's impractical (and I think you would agree). Can you imagine the force you would generate if you actually SPRINTED towards the highbar, and then TRIED to hang on? You would rip your hands open (if you caught the bar), and you'd have a terrible fall if you failed to catch the bar. I wouldn't wish either of those outcomes on anyone!
As far as simulating a vault from a JOGGING start is concerned, I never mentioned that one because I believe it to be inferior to #1 and #2. Why? Because the horizontal force generated by jogging puts too much force in the horizontal direction. Yes, this horizontal force will be converted to vertical energy by the natural "swing" of your body around the bar (and other forces that you generate as you grab the bar), but remember that in any PV drill of any kind, the idea is to focus on a single part of the vault (not try to simulate the entire vault - else you might as well just vault).
To explain a step further, the highbar is NOT like a pole, because the pole (other than the butt end) continues to move forward after it hits the box (it rotates to vertical); whereas a highbar is almost rigid (with only a slight give due to the flexibility of the steel bar). So this is why any highbar drill doesn't translate very well to a real vault when you grab it from a jogging start.
There is SOME value in doing a pullover (or perhaps even a semi-shoot-to-a-handstand) from a jogging start, but I think the horizontal force generated is too much of a disruption for getting your hips up and over the bar (and ultimately into a handstand on the bar). This is just my opinion (based on my personal experimentation), your mileage may vary (if you've also experimented with this).
I have tried this (without much success), so it's not as if it's new to me. Mostly, I used a jogging start just for the initial action of grabbing the bar and getting a bit of a swing going (stopping the drill well short of trying to swing up and over the bar).
So I would rank the 3 drills that best excercise the muscles of an elite vaulter trying to improve their inversion technique as: #1 - shoot-to-a-handstand from a standing start; #2 - shoot-to-a-handstand from a kip or cast-off; and #3 - from a jogging start, just reach up, grab the bar, and swing a bit (don't try to invert into a handstand - as you will either fail miserably, or - if you're a super-human elite athlete - in gymnastics or PV or both - you may be able to invert with no problem).
In any case, my opinion is that #3 will not help you to LEARN how to invert (by either swinging, pulling, or some other way).

I can understand why you might say this (I agree 100% that it's a great strength/explosiveness exercise), but remember that it's just a drill. So as a drill, it's intended to MAKE your body move super-fast, WITHOUT the "boost
" of inertia that you get in an actual vault.
That was my main point to Branko - if you isolate the action down to just inverting from a standing start on the highbar, it carries over very well to the vault (more so than from a kip or cast-off). At the risk of repeating myself, I will also say that this probably isn't something that you can just theorize about to truly understand. You MUST experience this first-hand, or it's more unlikely that you'll believe my recommendations here.
Try it - you'll like it!
