Character speed = 3600 / median reaction in ms — the fastest sending speed whose inter-character gap still fits your reaction. Overall speed = correct characters per minute ÷ 5 (PARIS).

Sent with straight PARIS timing (no Farnsworth padding), no hints, characters drawn at random with no immediate repeat. Overall speed = correct characters per minute ÷ 5, timed key to key over the 99 gaps, wrong keys included. One row per operator: their best run. The server issues each run, rebuilds the characters itself, recomputes every figure and checks the timings against its own clock. It cannot see your keyboard, so a determined cheat can still fake a plausible run. Treat the board as friendly competition.

Tug-of-war

Two operators copy the same characters and push a marker toward each other's edge.

Match

Both sides hear the identical sequence. Each character arrives the moment your last one is right.

Force: a correct first-try character pushes by (reference reaction ÷ your reaction), capped at 2×, times a weight. A wrong key pushes back 0.75 of a push; the character you then get right is worth 0.3. The marker moves (your points − theirs) ÷ 10. Handicap: the reference and the weight come from each operator's median reaction in their accepted ranked runs on this server (800 ms if they have none), so a slower operator's good copy counts for more. The server referees: it holds the characters, judges every key and scores every push. First off the edge wins; after two minutes, whoever holds the marker on the far side.
