Drew, let me remind you that you did say:

But I get the sense that you're not wanting to accept my criticism. This is a little contradictory, don't you think?
Strangely enough, #4 was what I consider my most important point, yet you consider it "opinionated". I'm very sincere about this point, and you should study both Bubka and da Silva's technique (there's lots of youtube vids to review), and think about why they hardly have to do *anything* at the top of their vault. Yet they *fly* off the pole.
My definition of a "free takeoff" is not quite what you think. There's no such thing as a perfect takeoff, so what I like to see is to hit your "ideal takeoff" point plus or minus a couple inches. That gives you some tolerance to play with, which means you can be under by a couple inches, or your can be "out" by a couple inches, and you'll still have a free takeoff.
But in your takeoff, you're under by closer to a foot than a couple inches. I can't be sure how many inches you're under (a foot is just a guess), but you're under so much that I can tell that it's nowhere close to being a free takeoff. Another way *you* can tell if it's free or not is to feel yourself jumping into the pole (or not). Most likely, you feel the pole jerking you off the ground (rather than you having time to jump into it).
I note that you said:

This is good, but it's not apparent in you vids, so you have to keep working on this.

How much is "my fair share"? However much you've done, you need to do more. At least 3 times per week. Especially if you're a 17-foot vaulter wanting to become an 18-foot (or 19-foot) vaulter.
Here's a challenge for you: Can you do the pull-to-a-handstand drill? You do it by standing under the highbar; jump up and grab it; then pulling yourself into a handstand. I'll bet you can't. But if you ever want to become an 19-foot vaulter, this is one drill that will help you do that. (Personally, I could *almost* do this drill - but not quite. But I kept working at it. It's not easy. And the hip-circle-shoot-to-a-handstand is a drill that will help you to do the pull-to-a-handstand drill.)
Re to push or not to push with your lower arm ...
I agree that Shawn Barber pushes. Lavillenie does too. So does Kendricks. I disagree that Brad Walker pushed (much). And I agree with the fact that there's more than one "proper" technique. However, the one thing that I'm certain of is that Barber, Lavillenie, Kendricks, and Walker have all learned how to do a "free takeoff", and have all learned how to *not* block their swing by any bottom arm push. Comparing their technique to yours, you *are* blocking with your bottom arm, which is killing your swing.
With all elite vaulters - the ones I listed above plus Bubka and da Silva (the Petrov Model vaulters), they swing in a continuous motion from trail leg down-and-back to trail leg extending straight up and over the bar. There is no hesitations; it's one continuous motion.
Until you can do that, I wouldn't be too quick to defend things that aren't working for you; and to ignore advice that will improve your swing.
p.s. I'll give you some hints about pointing your toes in another post - at another time. It's not very important right now.
