In your drawing, where is the pin?
In the 315 degree instructions, the pin-CG distance should be 0-1", and the pin/CG cluster should be relatively high to promote length (I believe), as this is not a go-long type of drill. I believe the pin/CG should be around the height of the ring finger or even higher. The lower the pin (id yours near the grip center?), the earlier the ball will want to roll.
