New member here, but long time lurker. I play blackjack and like to play poker as well. Have been fairly successful playing blackjack, but the other day I got rocked for 4,000 at a midwest casino in two consecutive shoes. Both times the running count shot up right away within 2 decks and I lost both shoes to the tune of 2k each give or take. So that's about 1 hour. I backcounted both shoes and jumped in at +1 and basically was placing close to max bets most of the shoe. I would say average bet of 2 hands of 150 for most of both of the shoes. What is the SD and z-score for this occurrence? I couldn't believe what I was seeing. My top wager was 2 hands of 200 and my minimum bet at +1 was 2 hands of 50. The pen was about a 1.8 cutoff from an 8 deck shoe and the ruleset was H17, DAS, and surrender.

Hopefully some of the math guys can chime in. Also what are the odds of 2 shoes going up to TC +5 or higher consecutively?
