How this data is measured

How riftcamp's champion statistics are collected and aggregated, and the limits to keep in mind when reading them.

Collection

  • Champion win/pick/ban rates are collected once a day (around KST morning).
  • On each stats page, “Stat date” is the date of the data and “Updated” is when it was last collected (KST).

Tier bands

  • Stats are split by tier band (Common, Diamond, Master, Challenger, Apex).
  • Champion Ranking defaults to Diamond and a 1% minimum pick rate to reduce extreme low-presence rows.

Lanes

  • Grouped into five lanes: Baron (top), Jungle, Mid, Dragon (bot), Support.

Metric definitions

  • Win/pick/ban rates are all percentages (%).
  • Net change is the percentage-point (%p) difference between two stat dates.
  • Trend (%p/d) is the linear-regression slope over several days — an approximate average daily change.
  • JOKER “Seen” is the number of captured snapshots a combo appeared in, not a game count.

Limits & caveats

  • We don't expose per-sample (game) counts, so figures based on few appearances are low-confidence and are flagged “Low sample”.
  • Data is not split by region or server.
  • The win rate on counter cards is the champion's overall (Diamond) win rate — not a head-to-head matchup win rate.
  • Patch 7.2 data uses snapshots dated on or after July 11, 2026.
