Compare natural-blackjack payouts
What the result means
The payout reduction from 3:2 to 6:5 is 0.30 betting units per player natural. The screening cost is action × natural frequency × 0.30. This isolates the payout change; it does not claim two tables have identical remaining rules.
Evidence record
Assumptions
Initial hands, a user-selected natural frequency, and a 0.30-unit payout difference.
Calculation
Added cost = wager × hands × hours × natural frequency × 0.30.
Limitations
Exact frequency and complete-game edge vary with deck and rules.
Frequently asked questions
Is 6:5 always worse than 3:2?
For the natural payout itself, yes. Compare all remaining rules too, but the payout penalty is usually much larger than ordinary favorable-rule differences.
Is this the complete house edge?
No. It isolates one rule change. Use the full-profile blackjack engine for supported complete packages.
