MH/s is the author's share of blocks times the network hashrate estimate over the range: a statistical figure, \u00b110% or so at a few hundred blocks. gap p10: the 10th percentile of seconds between the author's block and the previous one; near zero means blocks released right after others' (withheld). drift median: the author's block timestamp minus when we first saw it; a few seconds negative is normal, positive is future-dated. consecutive: blocks authored directly after the author's own previous block. Timing columns fill in from when the exporter started recording them. burst \u00d7: consecutive self-blocks divided by the count expected from the author's share (blocks \u00d7 share); about 1 is normal, sustained values above 2 mean blocks held and released together. Shown only where the expected count exceeds one. Cell colours: gap p10 red under 1 s and amber under 3 s; drift green in the normal negative band, amber once future-dated, red past 5 s, blue when more than 20 s in the past; burst amber above 2, red above 4.",
