Top ratedStats
Bar charts count unique accepted problems (merged with the global problem set for rating and tags). Heatmaps use UTC calendar days. Rating squares are sums of newRating − oldRating from user.rating when System update time falls on that day. Submissions count every row from user.status (all verdicts), paginated until Codeforces has no more rows—heavy accounts can take a few seconds.
Unique accepted problems, bucketed by catalog rating (100‑point bands). Unrated = no rating in the problem set.
Each problem counts once per tag (same as Codeforces tags). Top tags shown; remaining mass in “Other”.
Sum of rating deltas on each UTC day (GitHub-style weeks, Sunday top).
Count of submissions per UTC day (includes every verdict).
