Each of the twelve long-run clocks drawn as a wheel of its own stages, plus Polybius's cycle of constitutions. The top of every wheel is a turning point. Move the year and every wheel turns together; pick one to read where it stands.
The marker goes once round the wheel between two dated turning points, so the wheel speeds up or slows down to fit the real dates. Before the first turn and after the last, it runs on the cycle's average interval; a hollow marker means it is running on that average, not on a dated turn. The dates are the same ones Clock Lab uses.
Stage names come from each author's own phase sequence. Where a stage starts and ends inside the interval is our illustrative reading, not the author's measurement. The red segment is the stage that contains the turning point.
The centre gauge is the share of the interval elapsed since the last turn (or still to run, for draining gauges), labelled with the force each theory says builds or fades. It is a position on the wheel, not data. Anacyclosis has no dates, so its wheel is set by diagnosis and never counted.
