which in turn describes this research paper
"A measurement of the Hubble constant from angular diameter distances
to two gravitational lenses"
https://science.sciencemag.org/content/365/6458/1134


The paper is behind a paywall, but the Abstract, which is public,
summarizes the results. Two gravitational lenses at z=0.295 and
0.6304 are used to calibrate SN distances. The derived Hubble-
Lemaitre parameter H_0 is 82+/-8, about 1 sigma larger than other
local determinations and 1.5 sigma larger than the Planck value.

As Phillip wrote, the observations have their uncertainties, but 50
or so lenses would measure H_0 independently of other methods.
