Visible Count Mechanics

[Fritz]

Looking for some opinions/guidance on showing the 10-second count (I am relatively new to basketball officiating). When I first started, I counted all 10 seconds with individual arm movements - and did the same on my 5-second inbounds count. Then had a supervisor tell me that it looks stupid with my arm moving back and forth that fast and to switch to an out (1 second) and in (1 second) motion.

I've tried doing that but it feels strange - especially on the 5-second. Yet when I go back to my old method and try not to move fast, I find my 10-second count is closer to 12-13.

Any tips? And do you always start a 10-second visible count when the ball is in backcourt, or do you keep it in your head unless there is defensive pressure or you get to 6 or 7 and the ball hasn't crossed yet?

Thanks!
