The meter speed number for a club indicates how fast the meter will move. The higher the number, the slower the meter speed.
The meter speed number for a ball indicates how much of a reduction in speed will be applied to the club you are using, think of it as a brake. The higher the meter speed number for the ball, the more braking effect will be applied to the club meter speed.
The ball's meter speed affects the club's meter speed, it doesn't replace it.
