The finishing figure and the highest figure tell different parts of the story.
What happened
The preserved report describes a £64,000 gain and a higher £93,000 peak. It presents Darnborough’s own account, including fluctuations and the absence of a claimed system.
The difference is £29,000 below the reported peak. That arithmetic is straightforward; the evidential status is not. A newspaper interview is not a full record of wagers and withdrawals, so it cannot establish every session’s return or the precise risk taken.
What the case teaches
A complete performance review needs at least four quantities: starting resources, additional funds introduced, amounts withdrawn and resources left at the end. A headline can omit several of them. It can also select the successful trip while ignoring unsuccessful ones. A peak-to-finish comparison adds information, but it still cannot replace a ledger or establish a repeatable advantage.
Does stopping after a win remove roulette’s house edge?
A stopping rule changes when the session ends. It does not, by itself, change the probabilities or payout of the next independent spin.
