There's no such thing as a better or worse bet selection in the random game of roulette. The only thing you can do with systems which makes any difference is to bet more or fewer numbers and use some form of progression. This will affect the variance but won't by itself give you an edge. The ONLY thing which makes a difference with regard to bet selection is the NUMBER of numbers you bet on. For any given number of numbers you bet, it makes no difference HOW you pick those numbers. Waiting for "triggers" or virtual bets, skipping spins, trying to complete a pattern - all nonsense and a big waste of time and effort. This is obvious if you understand even a little probability. If you want to calculate your probability of winning, do you need to take into account how the bets are selected? NO, you just need to know how many numbers are bet. If you're betting on 3 numbers the actual process of how you select them (which could be very complicated) is irrelevant. The probability is 3/37 every time no matter what fancy selection method you used. Free your mind from the illusion of bet selection - it just doesn't apply in the random game. If you don't believe me, next time you use your system, when the time comes to place a bet, pick the same location or number of numbers, but randomly (get spins from random.org or use excel to generate them, don't pick numbers which you "think" are random - they should be "genuine" random numbers). Use the same progression or money management, the only thing which is different about this system played in tandem with your usual system is the actual numbers/locations bet on. You'll see that over time, there is no difference at all in the results, and this must prove (since the ONLY difference between the two methods is the bet selection) that your favoured bet selection has no merit - it's no better than random bets.
