Starting the clock mechanic

[packersowner]

I used to be really good at starting the clock and going from the 12 o'clock position to the 6 o'clock (so to speak). However, I have found myself recently starting the clock out to the side of my body especially when I feel the table may not be able to see my arm. In other words, instead of starting the clock in front of my body, I will go from 12 to 9.

With that said, looking for opinions on starting the clock properly. Also, do you have a closed fist, two fingers out, 1 finger, or use your whole hand.

Seems like there are lots of variations between junior high and the NBA. Looking for a good high school or college standard to follow here.
