What is the longest sequence you have seen without 4 REDS ( or black ) in row ? 100,500 or 1000 spins ???
without 4 reds in a row...dunno never tried to find out...
The only reason anyone might want that answer is for the purpose of developing
a brute force attack using a progression. The problem with using a fixed target is
that you will likely hit it. Try adding another layer of complexity to your target. If
your 4 reds must occur on spins 11 - 14 only then it is way more difficult to lose
that progression. I also prefer to use a grand martingale so as only requiring 10
to 20 spins to make a session worth it. You are less exposed to hitting that deadly
sequence with 20 spins than you are with hundreds.
So I use several patterns that must hit at an exact moment in the session in
order to avoid hitting that more elusive four spins of death.
