Progressive Blackjack and Positive Expectation

The Casino in my area installed three Progressive Blackjack tables last June. The jackpot is now over $350,000. I have run the numbers, and I believe the game is now a positive expectation game for the players playing only Basic Strategy but I would like your feedback. First, for those who don't know the game, it is regular blackjack with a side bet of one dollar. The bonus payouts are based on the player getting aces according to the following table;
1 ace in the first 2 cards - $3
both of the first 2 cards aces - $15
both of the first 2 cards suited aces - $30
first 3 cards aces - $100
first 3 cards suited aces - $1000
first 4 cards aces of same color(not necessarily suited) - Progressive

The odds of getting the 4 aces of the same color are approx. 393,000 to 1. If all other payouts are taken into consideration, then the $1 bet is a break even bet with the jackpot at approx. $268,000. If we then calculate the house edge of a $5 BS player over 393,000 hands, we find it to be around $12,500. So this means that when the jackpot is over $280,500, then the BS player has a positive expectation. With the jackpot now over $350,000, that expectation is quite significant. I would like to know if anyone else has had any experience with this game and if the game has shown high jackpots in other casinos.
BTW the rules in this casino are H17, DOA, split aces only once, 6 deck, 2 cut off

achieve your optimal utility.

There used to be a similar jackpot in a couple of casinos in my region, now discontinued. These were 8D games, deeply dealt. There was no pay on a single ace, but the other payouts were higher.

The cycle for the jackpot was so big (1/541k) that I never really expected to get that monster 'jackpot from heaven'. And I never did. But I still made a small profit on the sidebet by keeping an ace sidecount and betting only when there was at least one extra ace per deck remaining.

My spreadsheet doesnt easily adapt to your particular payout structure, but I suspect some of your figures need rechecking. Off the top, I get a (6D) jackpot frequency of 1/391190. An A as either of the first 2 cards should occur about 1/7 of hands, and if it returns $3 then this piece of the pie alone will account for c$165k and the breakeven will be much lower than your figure (i guess it to be c$150-170k).

Hope this helps.
