Boards
XP is capped daily, so every board here is really a consistency ranking. The weekly board resets every Monday, which is the one anybody can still win.
Streak · current
The flagship. Hardest board to fake, because XP is capped per day and a streak cannot be bought with volume.
Streak · all time
The hall of records. Broken streaks stay on it.
Level · with prestige
Prestige stars first, then level. A prestige 2 outranks a fresh level 90.
XP · this week
Resets every Monday at 00:00 UTC. The board somebody who joined yesterday can still win, which all-time boards never are.
