Does it have a random card generator or does it go through a certain number of decks before it resets? If it uses random cards then there probably is no correlation between winning and losing. If it goes through a certain number of decks then you usually are getting the larger cards when you are winning thus lowering your chances of winning after that. Conversely, if you are losing the count will usually rise giving you a better chance at winning. Every senario will be different but I think your strategy would hurt you more than help you.
