The only RNG that qualifies IMHO, is the unique result/being there combination of reaction to numbers, physics and live people, because no matter how many millions? of combinations you load into an electronic 'test to destruction' program, it all changes when your idea or 'system' is combined and applied with real cash money at a B&M casino.
As dobbelsteen so accurately pointed out, long run results and percentage indicators (no matter how they are arrived at), mean little when the physical, playing environment is only a few hours long.
That doesn't even register against short, medium or long run data.
Lets see, 25 Sph x 3Hrs x 4 Dpw x 25 Wks = 7500 Spins.
We would all be severely dead if that sort of regimen was demanded.
I could'nt do half of that and I have lots of stamina.
Not to trivialize recent events, we need some optimism in our chosen path. Later...Ringmaster
