Test Vertical Takeoff and Rotation

1st QUESTION: How should the kicking foot be planted at take-off with respect to the bar and the drop zone?

Aiming towards the drop zone, not parallel to the bar, at approximately 30 degrees
Parallel to the bar to extend the curve
Completely perpendicular to the bar with the heel elevated
Facing the starting point of the race

Pushing vigorously upward and slightly toward the opposite shoulder, crossing the body
Staying extended behind to avoid turning at the hips
Keeping low so as not to alter the center of masses
Moving toward the bar to move farther forward

Because this reduces the inertia of the stroke and better controls the flight
Because the verticality allows the previous inertia and rotation to project the athlete over the bar without knocking him/her down
Because jumping towards the bar increases the likelihood of overcoming it
Because the cushion is closer to the beat than to the fall
