For a second I thought you were Evan Miller who wrote about the exact same thing: http://www.evanmiller.org/how-not-to-run-an-ab-test.html

What he did in that article is more commonly known as an "A/A test"

Optimizely actually has a decent article on it: https://help.optimizely.com/hc/en-us/articles/200040355-Run-...

Terry was probably like 17 years old when he took his qualifying exam? Interesting quote considering his later work:

"After this, they decided to pass me, though they said that my harmonic analysis was far from satisfactory."
