Nice article by Frank Scoblete. The book he recommends is dated, but the principles still stand.
There are many flaws in his theory.
_He assumes (like every one else who doesn't believe in systems), that the doubling or the progression ( not all progressions involve doubling), goes on for ever until you either win or run out of money or you hit the max limit. Nobody addresses a situation
where the progression has a limited span, guided by experience.
Not every situation involves ALL or NOTHING.
_The same following a trend or going against a trend. There are limits on betting on trends or against the trends. Again experience is the key.
_ He mentions betting on a single missing number. No serious system player bets indefinitely on one missing number. Everybody knows that a single number can sleep from 10 spins to 500 spins. Betting on that number is stupid.In other words this guy makes it look impossible to win with a system so he can sell his book.
His arguments are no different than those who sell miracle color sprays on TV, that can fix minor scratches on cars. But when you buy it, you find out that you wasted not only your money but your hopes too.
No dealer can spin the ball with the same exact speed, or the wheel in the opposite direction.
Even a .0001 mph difference in speed can send the ball on a different diamond or no diamond at all.
Dealer signature is rather a coincidence. When we observe it, it's usually too late, or about to stop.
If you can take advantage of it while it last, then fine.
