A.R. 130. Team A coach requests a timeout for an official to assess whether a correctable
error has occurred. The error is (a) correctable or; (b) not correctable. RULING:
In (a) when the error is correctable, no timeout shall be charged to Team A. In
(b) when the error is not correctable, a timeout shall be charged to Team A. When any
portion of that timeout remains after the review of the request has been conducted,
Team A shall be entitled to use that time. When the review requires the length of a
timeout or longer, play shall resume immediately from the point at which it was interrupted
at a designated spot.

I would think only one conference, only one timeout. The number of contested calls is not addressed
