Found this tidbit on another site:
How is this going to work from a practical standpoint? Will coaches have to use a challenge TO? Is there a time limit involved? Will you be forced to find more midnight buffets?
Inquiring minds want to know.
That was my tidbit, and I expected this question, which has worried me for some time now.
The state has offered little guidance on how to handle the issue overall. Yes, it's a challenge TO, but no time limit. We are to stop the game, answer the coach's question, and if requested show him something in one of the books that backs up our ruling. I will say only that in my association, some white hats are better prepared for this sort of thing than others.

Nothing says how many times a coach may request a conference and consultation. For my crew, I will follow something like the pro procedure: they get 2 challenges, and a third if 1 is successful. That's, I have to hope, a straightforward application of rule 1-1-6.
