Just finished 12000 spins to see what happens. .... first I waited 8-900spins and start betting. That was to late. Then I start look every 100 spins.....this works just fine (flat betting 1 unit till profit and stop) It just works on the numbers. But it makes 2-250€ profit on 1000spins. I gonna keep testing this. (Just bet the number(s) that are far behind) ..
So in a way your using GUT theory of watching the 0x's
