When you call a charge?

[JC]

At the consistent request of my HS assignor, I do all 3 with the same hand in all HS games. I do them very fast to help sell the call. I put the fist up and down as fast as possible and immediately go to hand behind the head (Kelvin, I try to avoid the head behind the hand. That kind of looks like a British salute). Then point with open hand.
I agree that while the fist is in the air, it appears you are indecisive. Thus, I do it as fast as possible.
