Hi Phil, You surely have the skills! I have simulated the Super 4 side bet using your tool. In my sim, I used Wizard’s Super 4 Pay Table Version 2 and set the Jackpot as $300,000. I played 40,000,000 blackjack hands to average the results and found the HiLo trigger TC=+5. This result agrees on my earlier calculation based on the ace density. However, within the range +5<=TC<=+13, the gains at different TC levels behave like a jackpot. This indicates that HiLo is not efficient for this side bet.
A little more details. I haven’t seen Versions 1 and 2 paytables in any casinos, but I’ve played Version 3 and 4 in different casinos. Versions 2, 3, and 4 are similar, but Version 3 is cheaper. There is no reason for casinos to use Version 1 because its hit frequency is about 5%. Also, I find there are some typos/mistakes in Wizard’s Version 4 report.
