World Rankings

Ranked by the Euler Index: Level first, then the adventures finished at the Level (the k/7 beside the Ei — so 7/7 at 86 ranks above 2/7 at 100, and a climber just arrived at Level 4 ranks above every Level 3 climber), then Accuracy, then career Eulos; climbers level on all four share a rank (1, 2, 2, 4). A period board (this week, this month, Swiss calendar) ranks by the Eulos earned in the period and lists those who earned in it, so a new climber can top a board within weeks. Sort the same rows by any column from the head; the rank stays the Index rank.

The Altitude printed here is the worldwide one: of every 100 active climbers at the row's level, worldwide, how many have an Accuracy at or below the row's — so that the figure next to an Euler ID has one checkable meaning; the Profile shows the same Altitude among the climbers of a country or an age.

A rank needs ten answers at the level and a finished adventure within the last ninety days; until then a row reads climbing. A view with fewer than 10 ranked climbers lists them without ranks. The Δ column is the movement since yesterday's build on the worldwide all-time ranking: ▲ up, ▼ down, · unchanged.

A row shows, left to right: Euler ID (always) · alias (only with the parent's specific consent) · country (always) · the Ei with the age in brackets · Eulos as L · level · career · pace (p/a): the current Level, Eulos earned at this camp, everything ever earned, and pace, that is Eulos per year at this rate (career ÷ months since registration × 12; the first three months count as three). A Level n problem is worth n × n Eulos. Eulos are earned for problems solved, recoveries and finished adventures only; nothing spent is ever deducted here, and the purse is private and never on a board. The school is never shown next to a child, on any board, in any form; no gender, no birth year on its own. A withheld candidate has no row at all; a withdrawn alias disappears at once. The rankings are rebuilt once a day at 05:00 Swiss time, never live.
