Estimated hashrate is the author's share of blocks over the range times the
network hashrate estimate: statistical, roughly ±10% at a few hundred
blocks, and labelled as such. The timing columns join the new per-author
histograms (lair/quantus#12) on the preimage; outer join filtered to the
top-20 rows from the blocks query so authors without timing data still
appear with blanks.
