The same market priced at three books. Covering both sides across 2 of them against covering them at the cheapest single book, on 10,000 of turnover:
| Split across books | +0.010% — costs 1.00 |
| Cheapest single book | +3.981% — costs 398.10 |
| Difference | 397.10 |
This is a cost calculator, not an opportunity finder. A positive hold is money gone; low hold is cheaper than the obvious way and it is not free. Whether the turnover buys enough rollover progress or account longevity to be worth the cost is your judgement, and a tool that answers that for you is selling something.
Where the number comes from
Everything above was computed by the same engine that prices bets, at the moment this page was built — not typed into a template. The build fails if a figure appears here and not in the engine's own output.
