Even if the crowd calendar is right (a broken clock is twice a day), a good plan on a crowd level 8 day trumps a bad plan on a crowd level 3 day. A core plan that will succeed as is, but allows for flexibility due to the unexpected is what you want. But, when I say 'unexpected', I'm talking about things like ride breakdowns, weather events, etc. Tangible things. A crowd level prediction by Touring Plans, or anyone else, is a guess, and not something I would react to.
