Scorekeeper here - Alertnating Poss. Arrrow Question

[grizwald]

Hey guys,

I keep the scorebook/scoreboard sometimes for my daughter's teams.

I had a question for you guys:

RE: The alternating possession arrow.

I had been told to not switch the arrow until the ball has been inbounded years ago (back in High School - when I also occasionally had scorekeeper duties).

I was told that the reason for this is that are some types of infractions on the inbounds where the arrow won't move.

The only problem is that I don't remember any more than that about the specifics.

So I was wondering two things:

A) Is this true or not?
and
B) If it is true, a list of types of situations both where the arrow will change and where it won't.

Any help would be appreciated, just figuring if I'm going to keep score, I might as well try to do the best job I can.

Thanks
