Summary
Seriously Good Barbecue Cookbook: Over 100 of the Best Recipes in the World (Fox Chapel Publishing) Explore BBQ from Texas to Memphis with Brian Baumgartner, aka Kevin Malone from The Office sits at the 68th z-normalized percentile across 5,285ranked books. The z-percentile differs from a raw star average because Rankquant subtracts each reviewer's personal baseline before aggregating — so a reader who rates everything 5 stars carries less weight than one who rates discerningly. Raw-average percentile is 83; the gap between the two measures how much bias-correction changes this title's standing. How percentiles are computed.
