QuoteI have tested several shoes and the "Authors System" has done very well

It is simple, it is a series of 4 bets and a 4 step martingale and goes like this:

bet 1- same as last
bet 2- opposite of last
bet 3- same as last
bet 4- opposite of last

on a loss do 1, 2, 4, 8

- Tweak proposed:

The method of selection of the Authors system for the three even chances used: red and black, even and odd, high and low. Each done separately.

Look at recent results: which one of the three does better? then it is selected to be bet for the next spin.

Progression is carried over the one that has the best results for last spin.

No matter if you win or lose the next spin is reevaluated over recent results to select which of the three has a greater number won in recent spins and then the process repeats.

This is very similar to the "killer" baccarat stuff
!!!!!!! Oxoxoxo

and that`s the way they lost 3  bankrolls( min)  104 years ago. LOL.
