Maybe moving (or cross-posting) the transcripts to the EA wiki would be a better way to get people fleshing out details? GitHub doesn’t make very small changes easy, especially if there’s then a manual process (going through you) to have them synced here.
It’s already happened once in these comments that someone has been curious about a section and gone to get a precise transcript of that section, it would be nice if these little pieces of work could be reflected immediately in the published document.
(I agree with your calculation, but that’s the geometric mean, not the harmonic mean as the article called it)
