Fox actually looking at that chart again with the pre/during OE week. It looks like in Jan08 and Aug08 those were the two times it didn't work. It being down pre OE/up during OE and vice versa. In Jan 08 we went straight down, and in Aug08 we went straight up for two weeks.
I guess 6 out of 8 isn't terrible in terms of stats. But the sampling size may be too small and I don't have time to go back 3 years.
