Plot to the field

How a fix is taken
Method / 3 sightsRation the signal
One vermilion ink, and it lands only on the figure that has just changed or holds the live reading. Never wallpaper.
Read the residual
Tabular mono keeps every number on the same column, so the gap between target and reading is legible at a glance.
