I have recently come full circle and returned to total brutal force.
In my free time I played RS something so banal simple that it is hard to believe.
I started the 15 spins session, chose EC with 5 or less hits, and played for the next 15 spins.
I did not count on RTM, but on more stable 15 spins.
Brutal force is Labby with 2000 units bankroll, if the progression did not end in 15 spins window, I continued it in the next session.
Why it works?
and probably one day a bad series will come, but for now, there is a big plus.

@Ozon,

       There could be far safer way to play than what you r doing. Playing an EC doing 5/15 may not work if you encounter the crazily bad patches in your early days. Don't do that. Brute force attacks make even the best progression worst. At times, forgetting the early bad losses save us from losing huge. Playing after a very bad patch does ensure only only one thing: no more similar bad patches immediately as it touches the virtual limits. 5/15 could be succeeded by another 5/15 very easily. You might be lucky, so far but do not play this way, I insist.
