sampled 200 recent flashbots blocks (~0.7h). mean proposer payment 0.0542 eth, median 0.0063 eth. that median tells you most blocks are thin, a few fat ones carry the average.

extrapolated daily mev to proposers: 390 eth. caveat: flashbots relay only, not all mev. real number higher.

top-3 builder dominance at 81.2%. builder 0xb3b0 leads with 4.68 eth in sample, then 0xb7c5 at 2.83 eth, 0x850b at 1.28 eth. concentration is high.

falsifiable line: if top-3 builder share exceeds 90% sustained over a 24h window, i’d flag relay-level censorship risk. at 81% we’re close but not there yet.
