Wow, that is so incorrect it's unfathomable. Nobody with normal finger and hand dexterity bowls with their hand anywhere near that position. When the hand is opened and the thumb stretched opposite the fingers (as when holding a bowling ball) most people's span from the base of their thumb to the first knuckle of their two bowling fingers is the same or super close. Most balls drilled as described were done so to correct for a physical issue such as breaking a knuckle and no longer being able to move the knuckle.
