How these stats are calculated
English Wikipedia · 2026-07-09 – 2026-10-06. Views use Wikimedia’s “user” traffic classification, not unique visitors. Quality marker: not rated in this snapshot.
Stats use capped logarithmic scaling. Attack: 800–1,600 from daily views (cap 50,000). Defense: 200–800, weighted 80% citations (cap 300) and 20% quality marker. Health: 2,400–3,600 from prose words (cap 15,000). Values are rounded to tens. Citations indicate documentation volume, not verified truth. No rarity multiplier applies.
