Here in lay the problem for pretty much every NHC forecast. You've basically hit on the head why NHC doesn't make wild prediction swings based on every model run. If you cry wolf too far in advance, then people will not take proper care the next time. If you're too conservative, then people won't have time to prepare. Unfortunately atmospheric prediction is still a challenge even in these days of advanced computer models. If you're a professor and in the end the Triangle area gets nothing, I hope you teach your students that it was better to over prepare than to under prepare. In the end it will have cost them and you money and time, but that's ok. In today's "everything right now" society, it's ok to take a pause out of your life for safety rather than play on the edge of the knife.
