Hah yeah you definitely do not have to brief the airport you are taking off from to the guy next to you three times. You just have to check once that the ACARS data is not only for the correct runway but correct airport as well. If you don't initialize the airports properly you could get takeoff data for 23 in CLT instead of 23 in OAJ for example.

The extensive briefings and taxi checklist are a cause and effect result of the CRW overrrum incident a few years ago.
