Last interval heard
—
The surge comes up out of the crust and something under it answers. The answer never arrives at a fixed
delay. It arrives at 30.8% of the way through the interval, every time — while the
interval itself gets longer every cycle.
Nothing sweeps and nothing fills. There is no bar to watch. You get a flash at each surge and nothing in between, and you place the answer by feel.
The interval lengthens by the same proportion every cycle. That is the whole assessment. Place against the interval you just heard and you will be early, every time, by exactly the growth rate. Place against the one you expect and you will be right. Every interval you have already heard is written in the notebook below, because that is what the notebook is for.
This assessment records every placement and its error as a fraction of the interval, and whether your error shrinks or grows as the drift accumulates. It is telling you so now. It will assess you anyway.
