ROI modeled

Same flat-stake backtest, but filled 2¢ worse than the whale.

ROI modeled is the same flat-$100-per-bet backtest as ROI backtest, but with a more realistic fill: you enter 2¢ worse than the whale did. It is the headline return figure in the research views because it’s less optimistic than the idealized version.

It still excludes fees and only covers resolved bets, so treat it as a forward-leaning illustration, never a promise. Past performance is not predictive.
