Methods & caveats
For each celeb-season, take the maximum week-over-week change in that week’s mean judge score. Multiple dances in a week are averaged first.
Coverage: seasons 1–35; 3,602 performances; 11,027 individual judge marks in the cleaned Ballroom Data SQLite build (Nov 3, 2026, America/Los_Angeles).
Known gaps: Season 31 Mirrorball winner is not tagged as Winners in the performance table (Charli D’Amelio / Mark Ballas is missing from our winners extract). Seasons 33–35 largely lack Kaggle ages/hometowns. Season 35 celebrity names in the wiki scrape are often first-name-only or garbled. Dance-style strings still include some unclean variants. We never impute missing values.

Scores are per-judge means on a 0–10 scale so 3-judge and 4-judge weeks are comparable. Marathons/relays/megamixes are excluded from style averages unless noted.
