The ShadowPass ranking is updated in real time after each completed battle, and globally after each event.
Updates during an event
While a competition is taking place, ELO points are calculated battle by battle. You can watch your score change live from the event page (the "live" mode).
Official publication
Once the event is closed by the organizer, the ranking is locked and then pushed to the national ranking. Expect generally a few minutes to a few hours depending on the size of the event.
Global recalculation cycle
A full recalculation of the national ranking is run every night at 03:00 (Paris time) to incorporate any adjustments and corrections to results.
