The Jesus Discoveries: 10 Historic Finds That Bring Us Face-to-face With Jesus
Two parallel scores from 12 calibrated reviewers and 26 raw-average reviewers.
Z-normalized corrects for reviewer bias (every reviewer re-centered onto their personal scale). Raw average uses simple mean across the broader pool including stddev=0 reviewers. The 26-point gap is the rating-inflation signature for this title — discriminating reviewers liked it more than the casual crowd.

Summary
The Jesus Discoveries: 10 Historic Finds That Bring Us Face-to-face With Jesus sits at the 55th 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 29; the gap between the two measures how much bias-correction changes this title's standing. How percentiles are computed.
