Formula for adamb

I have analysed adamb's payout table for his chipless BJ and came to the conclusion that the odds for this sidebet are in general quite fair. However the only situations that can be exploited are stiffs (totals between hard 12 and hard 16) against a low dealer upcard because these are the most sensitive to the count. They obey the following equation:
b*p = (100-b)*10 where b is the dealer's bust rate and p the payout
This results in the formula b = 1000/(p+10) which is the required dealer bust rate in percent for breaking even.
I found that a TC of +2 is enough to turn the advantage in favour of the player.

This is exactly what I was looking for, and supports what I was thinking. Thank you for boiling it down for me.

Against a dealer's low upcard for the same reasons.

I think also player's totals of less than 10, against a dealer's low up card, for the same reasons as stiff hands.

I just realized that I didn't post any numbers that dealt with situations like Dealer's up card of 5, and Player's total of 6. But, that pays a similar payout to that of a Player's total of 16. I'll get specific numbers at some point, but this is a rare occurance anyway.

I doubt that with a total of 6 against the dealer's Five you'll get the same payout as with a stiff since this situation is almost even. So the expected payout is around $10.
Because you might still get a pat hand the ev is no longer governed by the dealer bust rate alone and you need a different method to figure the required payout. Also, the ev is not changing so much with the count and you might never get into positive territory for this type of situation.
