Here is a good clip of how the contact point version of ghost ball is used.

As I have written before, I use the contact patch version of the ghost ball. The contact patch being where the ball meets the table. Babe Cranfield's Arrow is based on this concept.
Where the x is placed for the contact point in the clip, that x would be on the table representing the ghost ball contact patch and would be 1/2 cb from the ob on the same line from center pocket to the contact point.
The point of the arrow represents this x on the table. This makes it a very valuable training tool and very simple.
