Summary
Richard the Lionheart was published in 1979. It is credited to John Gillingham. It is shelved for adult readers. It is catalogued as a nonfiction biography and memoir title.
The calibrated sample is 5 reviewers — the ones whose rating history varies enough to place their own average — out of 6 who rated it at least twice. The sample-size-adjusted percentile pulls a sample that thin toward the corpus average. The cohort it is ranked inside is the 1970s, 15 books wide.
How the score was built
We compare the reviewers of this book against every other book those same people reviewed. Each rating is scored relative to the reviewer's own baseline, so a reader who gives everything five stars is measured against their own five-star habit rather than against a stranger's. Every reviewer then counts the same, so the result is a calibrated consensus rather than a star average.
- Global percentile
- Where Richard the Lionheart lands against every book we rank.
- In-cohort percentile
- The same comparison narrowed to its cohort — books published in the same decade, so a Victorian novel is judged against Victorian novels rather than against this year's releases. Ranked against 1970s books (15 books).
- AI-adjusted percentile
- The same reviewer-normalized score, corrected for how much confidence the sample supports: thin samples are pulled toward the corpus average. Each book keeps the share n / (n + 53) of its measured distance from the average, where n is its calibrated-reviewer count, and the result is ranked on the same scale as the global percentile.53 is the median sample size across everything we rank. Here n is 5.
