You did play only 20 hands, which is incredibly low for any realistic claim. These are the dealer cards in the 20 games:
20,20,bust,18,20,20,15(player bj),bj,18,bust,bust,21,bust,19,bust,20,20,19,21,bj
This makes 20-21 range hands 10, or 50%, with 5 busts or 25% of games, and 25% 19 and lower.
50% of high cards is nothing more than an unlucky streak on your end and any serious blackjack player can confirm.
Please do not make claims with false numbers.
now your being a tad deceitful on the hands I busted on what was the dealer hands? 18-20 like I said the cards given out could have been bad luck but I notice you didn't add the risked amount or anything else to substantiate the numbers either. Truth of the matter IMO still holds firm, it was unnatural and even with only 20 hands the dealer received 18 or higher in every single hand while my average hand was 13-16. If it looks like a duck, quakes like a duck, it's probably a duck. Just calling it how I see it.
