Throwing it in because we were aiming at the "experimental" designation
seemed to be the easiest way to resolve the non-progressing discussion when
it initially cropped up in August 2017. The topic was permuted from
nearest-fail to oldest-pass in January 2018 to make the calculation
algorithm and interpretation of the data point a bit clearer but I don't
think that anyone has changed their mind much from their positions in
August 2017 - unless, as Scott pointed out, the one person who insisted on
this has done so silently.
