Edie (Robin's friend) wants bowling tips from John but after her shot goes too far to the right, he tells her to move a few boards to the right. Wrong. Her shot needed to be more to the left, so she needed to move a few boards to the left, not right.
THIS IS INCORRECT. Eddie bowled with her right, the ball naturally curves to the left. Her ball had a very weak curve, if any. To correct this, the bowler needs two things: 1) to move a few boards to the RIGHT, and 2) adjust your target board. Any pro bowler knows that you don't actually set your aim for the pins, you set it for where the ball's curve overtakes the speed. Detective Kelly's advice was correct.
