Was there, reviewed the PR, can confirm. Hi Steve! Since then we've also tuned it up in a couple ways, in particular adding "skip" logic similar to fast reservoir sampling to trade some accuracy for the ability to not even look at the next N {M,G,T}B if you've already seen many many many matches. For non-selective searches over PB of data it's a good tradeoff, despite introducing some search-order bias.
