Strange behaviour of roulette ball falling

[borson]

I have analysed some roulette spins with sony vegas in order to get the time for each turn of the ball.
It is supposed that if the time that takes for the ball to complete a turn is higher, it means that its velocity is faster and thus the time at which it will fall off from the rim will be lower too.

For instance, let's say that the ball completes a turn in 0,5 seconds. Thus, it is supposed to be faster than when the ball completes the turn in 0,6s. Hence, the former is supposed to last more time in falling into the wheel than the 2nd. For instance, the 1st should last.. let's say.. 22s. and the 2nd 20s. That would be the normal.

However in the spins that I have analyzed (from several roulettes) I always get weird results.
Some "turn-times" are lower than others, and their final times are also lower than those of the other lower turn times. I mean, it is like if the time turn of 0.6s lasted more time in falling than the turn-time of 0.5s. Which wouldn't make sense.

Due to this and other strange things (some "turn-times" which are quite different, have the same or similar final times) I do not see that there is any nonlinear relationship or that it follows any kind of function.

I have been reading on internet some papers and articles and, it seems that if there is any kind of inclination, no matter how small that angle is, there are zones of the roulette in which the ball will fall and it would lead to biases. I do not know if it could be related to the outcomes that I have obtained.

What do you think?
Thank you all for your help!

I am not a roulette expert and not a gambler but as I see it, there are various physical factors that influence the outcome like the initial velocity vector on the ball, how much worn out are the various components of the system, temperature, humidity, moisture just to name a few. Now, in order to attempt to calculate precisely the whole motion of the ball during one "spin" you have to know every and each one of these factors precisely, which obviously can't be done. Also, it is highly unlikely that any two throws in a row can start identically i.e. with the exact same velocity. All these give - at least on average, a different bias each time. Even a dexterous croupier can throw a ball directed to a certain "field" of the disk but this is subject to some uncertainty and cannot be done for a specific point i.e. number..

On the other hand the whole thing can be controlled through artificial factors (like an electromagnet) that can give a "shot" at a particular instant and pull the ball prematurely. I don't really now if this happens but it could, at least in principle.

Are you sure that the wheel that you are using is not riged for better odds on the house's side?? hehe
