STATION LOG
The senior crew is out running the season's cases. Down in the instrument bay, every dial on the station drifts a little each week, and somebody has to true them up. Tonight that somebody is you.
Ten signals per sweep, drawn fresh from an archive of one hundred. Correct locks the dial and builds your streak. A miss resets the streak and shows the true reading. Run as many sweeps as you like; the archive reshuffles every time.
