Tested this one, and sad to say, results were not that good!
1/6 games won.
I played according to your rules Mr.J, played with 5u bets and +200win/-200loss, normally when i test a system i have a 20% wingoal (+100u/-100u with 5u bets) but i played with a higher stoploss and wingoal now, anyway...
i think playing with repeaters is another fallacy, just like playing with EC's are. You can get lucky sometimes, but most of the time you will lose (FLATBET) that is.
This is very similar to my old system "Juggler" but i gave it up, i don't know how it can be improved? Perhaps keep the bet to 1-4 numbers, another idea is to BEGIN bet when you have around ~6 repeaters...
Yes, there are violent swings with this system. I think 1000 units is the minimum bankroll when playing with straight up numbers due to the long waits between hits.
I've been testing this on the streets. Much less time between wins and not too few winning opportunities.
It could be done on lines as well but you lose a lot of wiggle room when you reduce the number of opportunities to win on.
