QuoteTalk to any programmer like Reyth and he will confirm this.
Reyth has played only once on actual roulette wheel and this was online studio, not real casino, so I don't think him as the proper person to ask.
When you see a summary of millions results you are looking at the ''destination'' not how you've arrived there...
If you really believe that roulette is unpredictable then the only two things which remaining are progressions and luck!
Sorry if I don't share the same point of view.
