Checks and captures

Player stats 1

The following five sections present various player-based statistics. See if you can spot your name in the tables. Most tables are sortable and searchable, but also have specified inclusion criteria.

Relative performances

Shows all players who achieved a performance rating (over a minimum of 5 games) that exceeded their initial rating.

For some reason, these performance ratings tend to differ slightly from the values that are shown on players’ Lichess4545 season profile pages. I don’t know why they’re different, but they’re similar enough that it doesn’t matter. For what it’s worth, I use FIDE’s method (which the website does too), and I ignore all unplayed games such as forfeits and scheduling draws.

Lowest ACPL

Only the top 100 players are shown. Min. 100 moves played.

Multiple single-figure ACPLs

Here’s a list of all players who achieved single-figure ACPLs in multiple games n over the season.

Player stats 2

Avg think time / game

The players with the highest average (total) think time per game.

Minimum 3 games played. Includes data on all qualifying players.

Time spent

The top 50 players by total clock time spent over the season.

Playing time

The top 50 players by total playing time over the season.

Player stats 3

Most draws

The players who had the most draws over the season.

Comebacks

Originally suggested by Lou-E.

This table shows players ranked by the size and number of comebacks achieved over the course of the season.

For this purpose, the size of a comeback has been defined as the difference between a player’s final score in a game (0, 0.5, or 1) and the worst evaluation during the game that they faced (which is then converted into a rough win probability for their opponent).

For example, if I were to win a game after Lichess’s server analysis gave my opponent a 75% chance of winning in a certain position, then I would have earned 1.75 comeback “points” from the game. My opponent of course would have earned zero points. If the game had been drawn, I would have instead earned only 0.75 comeback “points”.

Only those who played at least three games in the season and who have a positive average comeback margin are included.

Biggest upsets

Includes all players who defeated an opponent rated at least 50 points higher.

Repeated upsets

Includes players who achieved multiple wins over opponents rated at least 50 points higher.
