While tinkering around with the Carsch Star, I suddenly realized that the best EC bet(s) can be indicated by tracking the un-hit numbers in the last 37 spins. Simply list all un-hit numbers and count the number of occurrences of those numbers in each of the EC bets. The one with the most occurrences is the hottest EC to bet.
Of course you would have to be blind to miss all the people that decry hot numbers, saying they are a sure way to lose because your numbers will just sleep you out of the game. However, the difference here is that we are betting a GROUP of numbers which is an entirely different animal; the larger the group, the greater the safety. Also, bets can be withheld until a minimum number of occurrences within a single EC is met (an even split won't be enough).
I am making a note of this method so I don't forget to look into it.
