Have an answer to this question?
Answer:
Hello Ron. The RG Identifies how fast a ball begins to rotate once it leaves the bowler's hand. The United States Bowling Congress defines Intermediate Differential of RG as the difference in radius of gyration between the Y (high RG) and Z (intermediate RG) axes on a bowling ball.
