This is data collected on one of Cammegh roulette wheels. The blue line represents an average. Without much detail if I look above the line ad pick the point to play 9 pockets sector it may be around 21-22. Only area above blue lie can produce an advantage. Since it is much smaller than the bottom part the advantage can’t be big.
If looking 9 pockets sector the best positioned it may be 3.7 hits, but the average is 2.8 so the difference is only about 25%. It means if the player predicts the drop point perfectly the advantage would be 25%.
Because the data was collected with roulette computer together with rotor speed, I separated data to slower and faster ball.
Blue lines represent slower ball then 7p/s averaging at 5.6p/s and the orange data is faster ball averaged at 8.3p/s.
It is obvious that the difference of 2.7p/s makes significant influence on the balls behaviour.
The slow ball jumps mostly 22 pocket while the faster ball has wider distribution, you can see some picks at 9 pockets and at19.
If looking blue data, slow rotor playing around 22 may produce 2.2 hits. Because it is fewer spins the average is 1.3. This increased the possible advantage to 40% and even faster rotor can have ~25.
Sure here is a sharp border at 7p/s but with proper software analyzing we ca get a bit more.
It is interesting here that rotor that spins 4.5s per rotation is already fast when compared to 6.5s rotor and it makes such change on results.
How it looks in relationship to rotor speed.
