Another idea that have crossed my mind a few days ago is that I wonder if there are any correlation with other parts of the layout and wheel when we get something like 1,2,3,1,2,3... What I mean is I wonder if there is something else that could warn us of a possibility of a repeat.... Like the law of the third or something else....just an idea....
How about keep score of how dozens are hitting, Say 1stdoz 10,2nddoz 10, 3rddoz 4, you'll have watched or played 24 spins or 8 mini games of 3.
If betting against 1,2,3 with 3 quiet,surely you'd win your game,even if one game is 3,3,3 and 3 thats your 4, 3's done, win.
