About two thirds of the way through "Flaw of Averages". Thankfully the chapters are short but it's written for business students and is aggressively anti-jargon, which can be annoying at times.

It started off promising, with some hints about monte carlo methods implemented in spreadsheets, but kind of detours into statistics basics, layman summaries of the author's prior scholarly work, and various business consulting anecdotes. I did not, for example, expect to read a chapter on the FASB-II's flaws regarding options pricing. And a few are downright concerning a decade later. I would not, for example, brag about advising Wells Fargo executives on their employee incentive programs after the cross-selling scandal came to light.

The final chapters, which I have not yet gotten to, supposedly cover the solution to the flaw of averages. Given the book is 15 years old, I'm expecting it to be pretty dated implementation wise, but I might be able to apply it to Prometheus histograms or t-digests. And I've learned a few things, like Jensen's inequality, and found a few sheets demoing a sampling approach.
