Thorp has a passage on this in the "Mathematics Of Gambling".He calls it dealer signature.

Thorp suggests a system based on root mean square error presumably expressed in terms of pockets which is the sum of the error caused by where the ball drops off the rotor, the speed of the ball and finally the speed of the rotor.

In every case he looked at the error was much too high to get a predictive edge.

Now if your dealer really is spinning into those 12 numbers all of the time obviously you have a huge edge. But the dealer almost certainly isn't doing that. You probably noticed this during a relatively small number of spins. You get weird short-term phenomena like this but it is just how randomness works. If you take a larger sample you will see that the dealer spins into those 12 numbers about a third of the time.
