That's why the big threat is teams. The one actually doing the counting can play haphazardly and consistently lose money but they will covertly signal the partner who comes in with big bets when the situation is advantageous. The big better plays until the count favors the house again and then walks away. The counter keeps at it until the odds are again against the house and then they'll signal the next big better to come in and so on and so on until they win their set amount and move on to the next casino. It's not illegal. It's not unethical. It's merely unprofitable for the casino and they'll ban you if they figure out that you're doing it.
