Where the Kohi click test came from

The most widely used click speed format in the world is named after a Minecraft server that most of the people running it have never played on.

The server

Kohi was a hard-core factions server, popular in the mid-2010s, running Minecraft 1.8 combat. In 1.8 every swing registers, so damage output is bounded by how fast a player can click. Click rate stopped being a curiosity and became the difference between winning and losing a fight.

Players needed a way to compare, and a ten-second click test appeared on the server’s own site. The format spread outward with the players.

Why ten seconds

The window was not chosen by anyone with a stopwatch and a theory. It stuck because it happens to sit exactly where two abilities overlap:

• Long enough to expose fatigue. Peak click frequency lasts about six seconds. At ten, the profile has started to fall, and the number includes that.
• Short enough to repeat. You can take a Kohi test between two fights. Nobody takes a sixty-second test between two fights.

That combination is rare, and it is why the interval outlived the server.

Reading a Kohi score as CPM

The Kohi format reports clicks per second. Multiply by sixty:

Same measurement, same interval, different unit. When someone quotes a Kohi score, they are quoting a ten-second run — which makes it one of the few numbers in this field that arrives with its interval already attached.
