For someone whose PR is 13-6, this vault from 3 lefts isn't too bad, but still needs work.
Sorry to say, but physics doesn't have any special cases!
There are 2 obvious flaws that I see. There may be more, but I suggest working on these two first (but still keep working on takeoff, run, plant, etc).
1. Your so-called C isn't really much of a C. A true C would have the chest driving forwards/up much more. So you never do get to a proper C position. If you did, your downswing would be much more powerful (because it starts from an elastic, stretched position).
2. Just at the time you should be curving your spine into a bit of a tuck (as opposed to an arch), you throw your head back. Are you doing that purposely (maybe someone told you to do that?), or is it just a bad habit?
You should be able to follow my logic here: If you don't arch your neck, then your trail leg will move faster; but if you arch it, then your trail leg will slow down.
Arching the neck causes the entire back-bone to arch, thus the trail leg must fight this action. On the other hand, if the head is just held naturally (not arched and not tucking your chin to your chest), then your trail leg downswing won't be inhibited.
Try to stretch more to the C (shoulder stretching drills might help); and try to keep your head in a natural position while you swing.
