I call a balance point a static point or a zero momentum point, and there really should not be a static / stopped point in the pitching motion once it starts.
I believe in balance throughout the delivery, but it’s a dynamic balance that stays with you from first movement through the end of your follow through with the center of balance always on the target line. Does that mean that you should be able to stop and hold any position throughout the delivery? Of course not. That would be impossible. Yet another reason why balanced at the top of the lift as a check point in the delivery makes absolutely no sense to me.
I am at a total loss why that specific moment in a pitching delivery has become supremely important to have balance. To me, it’s no more important than any other point in the delivery.
