Lowest Base price feed head lag

Mobula currently leads Base head lag at 0.2 s (p50, 24h) across the 4 measured providers. Base targets a 2 s sequencer cadence on the OP Stack, so the chain itself sets a roughly 2 s floor below which no provider can publish: any latency you see beyond that floor is pipeline work (indexer, fan-out, edge). Measured by holding the sequencer's flashblock preconfirmation stream and timestamping each provider's emission of the same swap from us-east, eu-west and Singapore, so the zero point is the moment the trade becomes public rather than the hour its block will carry.
