Summary
The Gifted Stationary 2026 Square Wall Calendar, German Shepherds, 16-Month Animal Theme Hanging Calendar with 180 Reminder Stickers, Month Planner for Home, or Creative Spaces, 12x12 In sits at the 39th 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 41; the gap between the two measures how much bias-correction changes this title's standing. How percentiles are computed.
