Staking and Bankroll Caps
All models use fractional Kelly criterion for position sizing. Full Kelly betting maximizes long-term bankroll growth on paper but is too aggressive in practice, so the models use a fraction of the full Kelly stake to reduce variance and tolerate estimation error.
| Sport | Kelly Fraction | Max Units | Unit Size |
|---|---|---|---|
| MLB | 0.25x | 1.5u | 2% bankroll |
| NHL | 0.25x | 2u | 2% bankroll |
| EPL | 0.25x | 2u | 2% bankroll |
Sizing in units rather than dollars keeps staking discipline independent of bankroll size, and the max-unit cap means even the highest-edge play is bounded. For the reasoning behind unit-based staking, see the guide on units and bankroll management.
