Might have been 168 TH/s but it's much of a muchness, same anser option range. Thanks.

168m TH/s was the 7-day average ;)

I now see the ambiguity on the source page, thanks for pointing this out. It comments on the 7-day average, but also shows a formula for a 24h calculation, so it's not really clear. I am leaning towards the 24h formula, though. Thank goodness it does not matter for the settlement....
