New York is remeasured and two world bests are voided

node

Alberto Salazar wins the 1981 New York City Marathon in 2:08:13, apparently breaking Derek Clayton's twelve-year-old world best; Allison Roe also runs an apparent world best. A remeasurement of the course, carried out in December 1984, finds it about 150 m short of 42.195 km, and both marks are rescinded. Organisers had already added about 99 m for 1982. This is the case that shows why the short course prevention factor exists: a course that is 0.35 percent short converts every performance on it into a number that means nothing.

A node is not a place. Drawing it on a map would assert something about the world that no stored fact supports.
