Why do you assume intelligent people who make decisions based on this haven't tracked spend by week, spend by month, regression models and the five hundred other ways to try and model this? We're talking about trillion dollar industries and you're assuming they don't do basic sanity checking.

I did start out saying I simply do not believe them. They don't have data from the time they were down, presumably. That is a big hole in the data for one instance.

I'm sure they have a million ways to say its not my fault. I started writing a huge response about human nature and the incentive to massage stats but I think you will dismiss it. If a system is down its a great opportunity to get a blame hedge in case sales are not as good as you predicted. There is no incentive to take an honest look if a brief downtime really affected sales in a meaningful way. I doubt anyone even does look. They just say this it what it would have been in our models if the downtime did not happen.
