It's based on the average standby wait times at key attractions between 10 AM and 5 PM. Those fall into a roughly normal distribution, which we carve up into 10 segments.
The way we do the math, there should be an equal chance of an arbitrary day being higher or lower than its prediction. (That is, we don't systematically over- or under-predict.)
I'll ask the stats guys whether there have been more higher days than expected. Give them a few days to figure it out.
