Thanks for the feedback.
I wouldn’t call it cherry picking as that suggests I’ve seen the data and chosen the week endings for any other reason than them being 7 days at the end of the month.
If you're comparing Monday vs Saturday vs Wednesday, you're going to see somewhat / drastically different results.
There will be one of each of the 7 days In each dataset. Without data to support your argument I’m going to blindly disagree, and prove you wrong later 😛
How about I expand the results to cover a whole month each time? Would that account for this global Halloween phenomenon you speak of?
