3. A 'Tripod' indicate 3 legs, where is the third leg? Bi-pod seems to be the percise and correct term or triangle.

Dear Martee,

I believe the answer to your question can be found in the 1-L sketch.

The stationary post is the player's head.

If we can imagine now, a stake driven through our head and back (spine)right into the ground, then that is the stationary post in the drawing....which incidentally promotes a stationary head per 2-0-A-1.

Why the stake driven through the head and the spine?

Per 7-9 "...with the back straight from the neck down - not rounded at the waist. It is easier to control the rotation of a straight rod than a bent one."

Add our two legs and voila...that is the tripod.
