I saw the same show with the "Nerds" from MIT playing High Stakes BJ in Vegas almost every weekend. They played and won as a team, but were eventually barred from the casinos.
My Brother used to use a HP calculator to track all the cards in the 6 decks while playing in Canada. BUT since the stakes at that time were $2-$100, there was not enough spread to play properly. Plus his bankroll was also only a few hundred and he did not have the most self-discipline. Calculators were legal since the games were set up by the province for Sports Charities. It was kind of neat to increase our bets and watch the 10's roll out of the deck.
