Modern Blackjack nth Edition

In my book, Chapter Ten provides an analysis of the Lucky Ladies bet. The following payoff schedule is used:

Q hearts pair w/ dealer BJ – 1000:1
Q hearts pair – 125:1
Matched 20 – 19:1
Suited 20 – 9:1
Any 20 – 4:1

Results were an advantage at TC +7 (High-Low) but a better SCORE at TC +9. A reader found a better payoff schedule as follows:

Q hearts pair w/ dealer BJ – 1000:1
Q hearts pair – 200:1
Matched 20 – 25:1
Suited 20 – 10:1
Any 20 – 4:1

So, what are the results? With this schedule, the bet becomes advantageous at:

High-Low: +5
REKO: +6
FELT: +9

As with the original analysis, due to the inherent risk in a side bet with a high payout, the SCORE can be improved by delaying the bet to a higher count. The following plots the EV and SCORE using High-Low, six decks, for no bet and bets starting at true counts of 5, 6, 7, & 8.
