DEFINITIONS
Backend BC (BBC): The total number of boards crossed from the breakpoint to the entry board at the pocket. Hook Power: This is not about ball speed but rather is an indicator of how strongly the ball moves horizontally toward the pocket from the breakpoint. A higher number indicates a strong move to the pocket while a lower number indicates a smoother movement. Total BC (TBC): The total number of boards crossed from the time the ball contacts the lane until it enters the pocket. Alpha Angle: Calculated by using the launch angle and the entry angle to compute a total angle change (the movement of the shot).
