| Input Scale | Standard Output Range | Variance Band | Recommendation |
|---|---|---|---|
| Low Baseline | 0.00 – 25.00 | ±1.5% | Optimal for conservative estimations |
| Median / Standard | 25.00 – 100.00 | ±0.8% | Benchmark standard for commercial workflows |
| Elevated / High | 100.00 – 500.00 | ±0.4% | Recommended for high-throughput modeling |
| Extreme Maximum | > 500.00 | ±0.1% | Verify input constraints for boundary saturation |

European roulette has 37 pockets (single 0) resulting in a 2.70% house edge on all bets. American roulette adds a second green pocket (00, total 38 pockets), nearly doubling the house advantage to 5.26%.
The highest payout is the Straight Up bet (wager on a single specific number), which pays 35 to 1. A $10 winning bet yields $350 in profit plus the original $10 stake returned ($360 total).
No mathematical betting system can alter the negative expected value of independent casino roulette spins. Table betting limits and finite bankrolls guarantee that Martingale progressions eventually encounter catastrophic loss streaks.
