How the stats work

ChinoizeCup is an online One Piece Card Game tournament series played several nights a week. After each event, its final standings, every round's pairings and the submitted decklists are imported from the event's public page on Limitless TCG. Those three things are the raw material; every ranking, rate, matchup and summary on this site is derived from them.

Special events (Heroine Battles) are one-off events outside the regular series, so they are left out of the meta statistics. They still appear in the tournament archive.

The meta changes every time a new set releases, so most pages show one format at a time. A format starts with the first event in which cards from a new booster (OP) or extra booster (EB) set appear in submitted decklists, and runs until the next set appears. Some formats are defined by other changes: OP-16.5 covers the wave of starter decks released mid-set, and OP-17.5 starts with the ban list that took effect at ChinoizeCup #115.

Pages show the newest format by default, as soon as its first event is in. Early in a format the sample is small, so check the event count before reading too much into the numbers. Every format, and All Time, can be chosen from the format menu.

Events tagged [EGB] form a separate series. Leader rankings, trends, card and decklist statistics show either the Standard series or EGB, never a mix, because the two attract different fields. Player rankings count both.

A leader's numbers combine every entry piloting it within the selected format and series.

Win rate

Match wins divided by all matches played (wins, losses and ties). Byes and drops are counted as recorded on Limitless.

Play rate

The leader's share of all entries: how much of the field brought it.

Top 4 rate

The share of entries that finished in the top 4. Players who dropped are never counted as a top-4 finish.

Conversion

Tournament wins divided by top-4 finishes: how often the leader closes out an event once it reaches the top cut.

Average placing

The mean final standing of entries that played the event out. Lower is better.

Meta Impact

Win rate multiplied by the square root of play rate. It rewards leaders that are both strong and widely played, and is shown for context only; it does not affect the ranking.

Pilots

The number of different players who entered with the leader. A leader with many pilots is less dependent on one player's skill.

Matchups

Built from round-by-round pairings: every match between two players is credited to both leaders, giving a head-to-head record for each pair.

Leaders earn ranking points from results: 1 point for every top-4 finish and 2 more for every tournament win, so winning an event is worth 3 points. The ranking orders leaders by points, with match win rate breaking ties.

Tiers are relative to the rest of the field. The top 10% of leaders by ranking points are S tier, the next 25% A tier, the next 30% B tier and the remaining 35% C tier. Because tiers depend on results rather than popularity alone, a deck played by few people can rank highly after a strong run; the entries column and the minimum-entries filter help separate a trend from a single result.

A leader with fewer than 5 entries in total is flagged on its own page as too small a sample to draw conclusions from.

The player leaderboard adds up points for every event a player finished in the selected format. Entries where the player dropped score nothing. Players on equal points are ordered by match win rate.

Every player profile includes a written overview of the player's results; profiles with at least 5 events are listed for search engines.

The monthly ranking follows the official ChinoizeCup rules. Only a player's single best finish in each week counts, so playing every night does not outscore one strong result. Entering at least one event in a week is worth 2 points even without a scoring finish. The top 7 at the end of the month qualify for the monthly final.

Ties are broken by, in order: best results (compared best against best, so two wins beat one win and a second place), the number of weeks played, and who reached their best standing first. A tie that still remains at the 7th seed is settled by a head-to-head match.
