A block crosses the wire every half second. The pen inks the clock tick. It does not wait.

Everyone has a personal equation

Your lag against a 500 ms block is a number. Measure it. Log it. Shrink it.

02 · THE DRUM

Line by line, the marks converge.

Black tick: the clock. Violet tick: your key. Each lock feeds a new line off the drum. The bracket between the two is the gap.

Rules of the night

Twelve transits a night. Three clean locks logs it. Three lost locks, or twelve transits without three clean, and the night is lost. The key recoils for 600 ms after each lock.

First night: turn on the guide wire. It shades the next crossing and widens clean to 60 ms. After two locks, press Apply equation to cancel your lag.
