Definition

A detection is live when the latest snapshot of the host carries it, and countable when its technology is not a web standard. HTML, HTML5, CSS, JavaScript, HTTP/3, HSTS, Open Graph, Priority Hints and RSS are recorded, shown separately and never counted.

Rule

A technology missing from the latest snapshot keeps its last verified date and is not counted. It is never reported as removed: the removal rule, two consecutive healthy misses with the standards excluded, is not in force, and until it is no page states a removal.

Denominator

The live detections on the same host, the standards included. The domain answer prints both numbers in one sentence.

Caveat

Detections are counted, durations are not. 8,269,013,125 distinct host, technology and day detections collapse into 3,267,680,596 intervals, so the average pair has been observed 2.5 times. No duration is read from a first and a last verified date.
