I'm a huge fan of statistics for reporting, but I think his ideas about how to use it in practical development is mostly broken.

Their team needed statistical analysis and charts to solve a 60 second response time bug? That's just a total lack of basic debugging skills.

Eliminating all confounding and spending the time to test your application's performance characteristics in a statistically valid way rarely makes sense. If lives are on the line fine, but in most cases the reason for even attempting it do so is bureaucratic. Release early, release often.
