Given that virtually all of OCEAN is mining with Knots, one way or another, it's closing in on 1% of the hashrate, I'd guess.

Yes. Ironically, with such small hashrate, a large fraction of the number of template-constructing entities also run Knots.
Today Ocean mined 3 blocks, and by dividing 3 over 144 I learned Ocean has 2.1% of hashrate
But that's only a reliable metric if they consistently get that many blocks per day (or more). Otherwise it's probably just luck.
Luck or not, the important thing is that (maybe) three nyms constructed blocks today, and Ocean was there to help them with variance.
