Interpretation
House edge uses the initial-wager denominator and the stated total-dependent strategy. Expected cost equals initial action × house edge. Actual action from splits and doubles is higher, but its average effect is already incorporated in the stored initial-wager edge.
Cut-card dealing and the site’s documented profile assumptions apply. Figures are not portable to 6:5 payout, restricted doubles, different split limits, early surrender, or other hole-card settlement rules.
