The top 9,000 players on the personal leaderboard can exchange fame points for a Tier X reward tank. The price equals the points of the player ranked 9,000th, so the line moves until the event ends.
Everyone else with 1,000+ fame points bids bonds; the 3,000 highest bids win a token for a tank. Losing bids are refunded.
Expected points per battle = win rate × points per win + (1 − win rate) × points per loss at your clan's stage (official table). Clans move up stages during the event, so points per battle grow over time — treat the result as a rough guide. Bonds for the auction come from rank and the clan multiplier and are not published, so only the bid history and forecast are shown for that route.
Beta. History comes from the past-events table and each event's final leaderboard (reward ranks were 10,000 in Mar 2024, 9,100 in Nov 2024, then 9,000). Trend = straight-line fit through the 5 events; the forecast range uses the fit's spread. Small samples mean wide uncertainty — please don't treat the numbers as guarantees.
