But if you carry it in front of you and use the left hand as a lever you can keep your right hand right next to your hip.
Altius: Why would it be a half step late? If the vaulter is not under with his take off,
the right arm should be fully extended right before the pole tip hits the back of the box.
The athlete in the following video uses the count I was talking about and I think it looks fine. Any suggestions on the video?

Having the top arm fully extended does not guarantee that the foot has took off when the pole tip hits the back of the box. You can still have the arm fully extended before the tip hits the back of the box and still take off under if your pole plant is not in ideal synchronization with the stride pattern and foot placement. The ideal time to have the arm fully extended is the instant before the take off foot hits the ground for the actual jump, provided that the jump happens in the right place. At this point the arms should no longer carry any weight of the pole so that the body is completely free to jump unabated. The ideal plant, by definition, is early.
It's not wrong to say that the extension should come before the pole tip hits the back, in fact that's what should happen. It's just missing a bit of detail with concern to the steps. I personally think of the plant as always related to the foot placement, that way you can practice it a million times without having a box be there all the time. Then I always relate the stride to a certain distance (with check marks in between) and a point of take off. That way you've got all your ingredients there ready to cook even without a box to practice with. I try not to worry about the box too much, it's not really going anywhere! But the plant timing, stride pattern and run up distances can definitely change! The box is just there minding it's own business when somebody happens to come along and stick a pole in it!
The plant I use is 6 steps (3 lefts), with the "plant proper" occurring 3 steps out. At 6 steps the pole should be at about 45 degrees - depends on the vaulter's speed, but at walking pace I say 45 degrees. The pole is lowered through the first 3 steps to about 10 degrees from horizontal on step 3. Then the plant proper happens on steps 4, 5 and 6. The pole transitions through horizontal on 4 and both arms move up ward through 4 and 5. Ideally the arms should both be extended the moment before step 6 hits the ground for the jump. At the very least the top arm should be fully extended, the bottom arm should be in a strong position if it's not possible to be fully extended because of a smaller pole. Sounds complex but get it down with your athlete and it's automatic. BTB2 has a great little cue that I really like - "one, two, three, plant, two three"
This is also one of the reasons why I use "steps" instead of "lefts" - it allows you to be more accurate with what you're describing to the athlete. You can miss a lot of details between 2 steps (1 left) especially during the plant! Using steps allows you to tell an athlete exactly where you want the hands and pole to be in a much more precise timing. I can't tell somebody that the plant proper happens 1.5 lefts out!

P.S. Sorry but I can't see your video. I've got problems with my internet at the moment.
