well i don't know for how many spins i've played this system, could be 2000 or 5000. but it doesn't matter to test a system for 10.000 spins! why? because what is working very strong for 10.000 could be a disaster 10.000 later. amd if it's working 80-90 % of the time i'm more then satisfied. amd what is the worst thing that could happen to me. when i play this system online, i play with 20 cent with a bankroll of 30.00 euro. i'm way beyond that. i'm now only playing with the money of the casino, never again my own. and i don't nees to amymore. of i will loose all 30 euro, well then that's to bad, i start a new one. from what i have seen and now i'm talking from my personal records, i have played this system now for 76 sessions and never lost my 30.00 starting money. like i said i play most of the time with 0.20 cent and stop when i have between 10-15 euro profit. when i have reached that, i won't return for the rest of that day and come back the day after. when i'm at my local casino i only play with 1 euro per bet, nothing more, nothing less, no progressions etc. for my local casino i also don't need to spend my own money amymore. so the make it short. no i don't have tested it for 10.000-20.000 spins. when something works, it works. amd when you play a system for a very long time om end, it will fail like anything else. there is no long time system. it is how to play it. and like my grandfather always used to say; life is like roulette, everyday is a new day where anything can happen, the only thing we do know are the numbers on the roulette wheel. 37 numbers and GREED is number 38!!!!
