Note

These projections assume your edge remains constant and you adjust bet sizes proportionally. In practice, variance means actual results will fluctuate significantly around these expected values. The compounding model assumes you resize bets after every hand based on current bankroll.

Formulas:
Flat: B_final = B_0 + (edge × bet_size × total_bets)
Compound: B_final = B_0 × (1 + edge × bet_pct)^total_bets
Doubling time = ln(2) / ln(1 + edge × bet_pct) bets
