A few things can cause a rank to look "off":
• The contest hasn't settled yet. Leaderboard rank only
includes points from settled contests. A contest isn't settled — and doesn't
contribute to your rank — until after the last game in the contest ends and
official statistics are certified. Settlement can take up to 72 hours.
• Stat corrections. If a contest's final stats are
corrected within 48 hours of settlement, your score and the leaderboard are
updated with the corrected value.
• Tiebreakers. If you and another user have the same
total points, the Weekly Leaderboard uses a tiebreaker rule. See "How are
leaderboard ties broken?"
• Weekly reset. The Weekly Leaderboard resets every
Monday at 5:00 AM ET. If you were ranked high on Sunday and see yourself lower
on Monday morning, the week has rolled over.
If your rank still looks wrong after checking these,
submit a ticket with the week, your expected rank, and what you're seeing.
