Colt - you've figured out SOME of your flaws on your own, and the idea that each flaw is due to a previous flaw ... but you don't have them ALL figured out yet ... becuz you haven't gone far enough BACK in the PV actions yet (other than mentioning your inconsistent run).
Between your "inconsistent run" and "looking at the bar" there's quite a few other steps that you've missed. I'd say ...
- becuz you take off "under" (just guessing), you get jerked off the ground (just guessing)
- becuz you get jerked off the ground, your body angle isn't straight up and down (or a little bit forward leaning)
- becuz you get jerked off the ground, you don't JUMP off the ground (just guessing). This is similar to your reference to a lack of lead knee drive. You need good knee drive to jump vigorously.
- becuz you get jerked off the ground, you CAN'T jump off the ground as well
- becuz you don't JUMP off the ground, you don't have a very smooth takeoff
- becuz you get jerked off the ground, you don't get a chance to pre-stretch into a good "C" position
- becuz you don't get a good pre-stretch, you lose a lot of energy at takeoff
- becuz you don't get a good pre-stretch, your downswing won't be optimal - your trail leg won't be stretched long and STAY long thru the chord
- becuz you don't get a good downswing, you won't feel that WHIP when you pass the chord (this ... to me ... is KEY)
- becuz you don't feel that WHIP, you won't be rotating upside down from the momentum of your downswing and whip
- becuz you aren't rotating upside down from your momentum, then EVERYTHING after that slows down
- becuz you feel EVERYTHING slowing down, you begin to look at the bar (you won't have time to look at the bar if everything is going quickly and "properly" in your WHIP, upswing, and inversion
- becuz you look at the bar, you slow yourself down even more
- becuz you begin to slow down, you flag out instinctively to maintain your pole speed (towards the pit)
I could go on ... but once you flag out and look at the bar, then you've lost the vault ... NOTHING after that is going to work very well!
I think you should also understand WHY you body flags out. Your instinct is to both reach the pit and clear the bar. To do both, you need enough momentum to keep going UP ... as well as enough momentum to reach the pit safely. If you don't have enough momentum to do both, then your instincts tell you to reach over the bar (and into the pit). This is a much safer alternative than striving to invert and shoot straight up ... only to stall out. That would be extremely dangerous! So you need to figure out how to maintain enough momentum for both ... to shoot UP (don't flag out) ... and to shoot OVER the bar.
One way is to simply lower your grip. Another is to simply use a lighter pole, which will give you a shorter chord (which will carry you into the pit more). But a lighter pole doesn't let you shoot HIGHER ... only LONGER.
Another way is to eliminate all energy losses in your technique ... such as the energy loss of a poor plant ... and the energy lost when you don't jump UP as well as FORWARD ... and the energy lost when you get jerked off the ground when the pole hits the back of the box ... and the energy lost when you don't get a good pre-stretch ... and the energy lost when you don't have an efficient downswing ... and the energy lost when you don't WHIP past the chord. I could go on ... but you get the idea.
You probably also have some flaws in your plant (too late? not reaching high enough?), but I would just be guessing at that too. If you don't have a good plant, that will also cause problems in subsequent vault parts.
Now ... these are WAY too many flaws to fix all at once, so I have 2 recommendations ...
1. Fix the earlier flaws first
2. Fix the biggest flaws first (the weakest link in your chain of PV actions)
A mix of #1 and #2 is probably best.
