One dot is one run, 16 in all. Height is the share of shots on a target outcome, 0 to 100% in every row, one row per physical pair. Tap or hover a dot for its value. The axis is the days something was run, evenly spaced: the gaps between days are not to scale. Runs on the same day are spread sideways so they can be counted. A faint vertical line is where a new vendor calibration began, shown only for runs that recorded it.

Tap or hover a marker to read its share.

One marker is one run, side by side where a cell has several; there is no line or band because either would need a summary of the runs. Each panel is one circuit width, and the dashed line is what a device returning random bits would score on it.
