Yes, I can understand your confusion better now, and yes ... (b) is a tuck. MY definition of a "tuck and shoot" is when a vaulter STARTS to tuck after they pass the chord, but then they HOLD ... or PAUSE in ... the tuck in the flat-back position. They do this while they wait for the pole (or in this case the rope) to roll forwards to vertical (or in this case for the rope to swing closer to the bar) ... and then they shoot. I'm sorry to confuse you about these 2 definitions of "tuck", and I accept your definition of action (b) being just as much a correct definition as mine.

Is this a flawed attempt at a specific drill that resulted in the tuck? If he was only working on (a) to (b) why did they go through the effort of setting up standards and a bungee to even do (c)?
I don't think (b) is unimportant ... I'm just stressing (a) more than (b). And I'm just saying that (c) is even less important.
Actually, (b) isn't THAT important, becuz it doesn't scale very well to a real PV. It's a matter of scale. If you're vaulting 10 feet, then you MUST tuck ... very much like the tuck you see in action (b). But if you're vaulting 20 feet (as Bubka did), then there's no need to tuck this way. You have loads more time to swing without tucking (much) at all. That's why I didn't emphasize (b) ... it doesn't simulate a real vault (for anyone jumping > 14 feet or so) very well.

If you said that this vid is rope vaulting with a "Bubka", then I would agree. By "Bubka" I mean his highbar drill of the same name. This is where semantics have confused all this ... and I'm probably more guilty of causing this confusion than you are. But when you specifically say "tuck and shoot" now, I take that as the type of action that you see in real vaults of the same name. A "tuck" during the upswing ... but then a PAUSE in the flat-back position ... while the vaulter waits for the pole to roll to vertical ... and then a "shoot" out of that "tuck" (also called "rockback") position.

No matter how that drill is initiated (run jump grab, platform, etc) the goal seems to be to clear the bungee. Yes there are multiple parts to be worked on but the goal remains the same. Run (run), Plant (transferr momentum to the rope), Swing (rotate on the rope to a vertical position), Clear (extend off of the rope and go over the bungee).
This is where I think RainbowGirl and I had a misunderstanding ... and you too. I'm not at all claiming that his intent was to make this a swing drill. I'm guessing ... just as you are ... that the INTENT is to clear the bar ... however he can.
Using any and all skills and experience that he could muster, Bubka did what he does best ... he rose to the challenge of trying to clear a bar set at a certain height. Whether intuitive or not, he did this very well ... wa-a-a-ay better than most mere mortals ... by having a quick and powerful downswing ... and then shortening the radius of his upswing. This is pure physics ... the quicker and stronger the downswing ... and the quicker the shortening of the radius ... the more MOMENTUM he's going to generate in the UPWARDS direction.
Even if he didn't INTENTIONALLY downswing and upswing this way ON THIS DAY, this is obviously not the first day that he's ever tried this drill ... and we know for sure that he's done a lot of stiff vaulting. So this is the culmination of all his other training ... including weight training and highbar training for the "Bubka" and "extension" part of the drill. After stiff vaulting and rope vaulting this way over multiple sessions (probably multiple YEARS), it should not be surprising that action (a) and action (b) eventually become intuitive.
I hope we're on the same page now. Caveman, I like the way you question everything. I hope I've satisfied your need to understand these drills in depth ... and I completely agree with your tag line.
Hopefully, you can agree to MY tag line!
