The central year is a source-reported first-known-use horizon, not an exact borrowing event.

The ten-year interval encodes circa 1540 as an approximate lexicographic horizon, not proof of coinage.

The open interval begins at the reviewed English horizon without assigning invented dates to later technical senses.

A twenty-year interval encodes the source’s approximate c. 1550 label rather than false exactness.
