Two parallel scores from 4 calibrated reviewers and 7 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 20-point gap is the rating-inflation signature for this title — the casual crowd liked it more than discriminating reviewers (a classic inflation pattern).

Summary
My Favorite KJV Verses to Color - Inspirational Adult and Teen Coloring Book Inspiration and Encouragement from God's Word sits at the 41th 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 60; the gap between the two measures how much bias-correction changes this title's standing. How percentiles are computed.
