Top Students by Net Points Earned
Net House Points by Book
Net Points by Authority Figure
Key Findings
- Snape made 20 point decisions across 6 books and every single one was a deduction — net -277 points, making him the harshest authority by far
- Dumbledore awarded 570 points in just 4 events, all massive end-of-year bonuses (50–200 each) that swung the House Cup
- 91% of recorded transactions (67 of 74) involve Gryffindor, reflecting the series' narrative focus
- Chamber of Secrets had the biggest swing: +475 net points from Dumbledore's 200-point-each award for defeating Tom Riddle
- Goblet of Fire is the only book with zero points awarded — only 4 deductions totaling -90
Point Magnitude Trends Across the Series
- The average absolute point value per event across all 6 books is 24.0 points, with a maximum single event of 200 points (Harry and Ron each earning 200 points in Chamber of Secrets)
- Book 2 (Chamber of Secrets) shows the highest average magnitude at 69.3 points per event, driven by the two 200-point awards — a clear outlier in point inflation
- Book 3 (Prisoner of Azkaban) has the lowest average magnitude at 11.2 points per event, suggesting point values were scaled back after Book 2's inflation
- 21 of 74 events (28%) involve 50 or more absolute points, concentrated in Books 1, 2, and 5
- Point inflation is not strictly linear across books — Books 1–2 escalate sharply, Books 3–4 deflate, and Book 5 re-inflates with 23 events (the most of any book)
