A TETR.IO statistics website.

PPS is the statistic that measures the speed of a given player. This is calculated by dividing the number of pieces placed by the time spent in the game, in seconds.

Where pieces is the total number of Tetriminoes the player has placed, and t is the time in seconds.

APM represents the frequency of damage a player sends. This is calculated by dividing the number of lines sent (received or cancelled by the opponent) by the total time spent in the game.

Where attack is the number of lines sent (received or cancelled by the opponent) t is the time in seconds.

VS score is a metric created for TETR.IO, made in order to approximate one's "skill score" in a Tetra League game. This is how it is measured:

Where attack is the number of lines sent, ds is the number of garbage lines cleared, t is the time in seconds.

APP has been made to measure the efficiency of a player, which means the maximum amount of garbage sent with the least pieces as possible.

DSPS is the amount of garbage one clears in a second, as straight-forward as it sounds. You can get its value by either having the time and downstack, or you can deduce it from the VS and APM.

DSPP is basically the efficiency of garbage. We can see that as the quality of Downstack, whereas DSPS is the amount of downstack. You could theoretically estimate quite well one's Downstack ability using these two values.

Where p is the total number of pieces placed.

CI estimates the shape of garbage a player sends. When it has a low value, then the garbage of the player will be cleaner, otherwise it'll be cheesier. Its equation uses multiple Basic stats.

⚠ Warning: not to be mistaken with DSPP
GE measures how well a player uses its garbage to backfire. If the value is low, then the player replies with cheesy garbage, otherwise it'll send cleaner garbage.

Win chance is as straight-forward as it sounds, although it is in this section because of how it is calculated. It is based on the glicko ± rd system. The value is in percents, for the first player (player 1 on the equation)

Where R1 ; R2 are the users glicko, and rd1 ; rd2 are the players RD. Result will be for the player 1.
