You should always consider 2 wins or 2 losses 
as the beginning of a trend. On the next wager 
you will act accordingly. This ensures you will 
never miss a trend no matter how short or how 
long it may be.

Your wagers will take advantage of the trend 
no matter how short it is.

You will get chips of various denominations. 
If you bet $5 chips, then you need $5 and $1 
chips. If you wager $25 chips, then also have 
plenty of $5 chips, and maybe even $1 depending 
on how accurate you want to be.

After 2 wins you will increase your wager by 1/3 
of your last wager.

After 2 losses you will decrease your wager by 
2/3 of your last wager. You will continue to 
decrease by 2/3 on each loss until you hit 
table minimum.

In the typical chop trend, you expect a win after 
a loss, and a loss after a win. So after 1 loss, 
increase your wager by 1/3. After 1 win decrease 
your wager by 2/3.

Your first wager should always be 3 times the 
minimum bet when you first begin playing.

This is the basics of fractional wagering. There 
are many finer points, tricks and tips that I have 
developed over the years, but I have neither the 
time nor desire to go into that much detail.

This method of play is very successful on any of 
the even chance wagers in the casino. My preference 
is Blackjack, but I have used it successfully on 
bac and roulette.

You will not win large sums of money every time you 
play, but you will stay very close to even most of 
the time, lose very little when you lose, and you 
will occasionally win large sums when you hit the 
inevitable win streak.

You begin playing at anytime. 3 times the table 
minimum is your first bet. 

You were close:

25 red / win  / +25
25 red / win  / +50   (2 wins so increase 1/3 to 33.00
33 red / win  / +83   (+1/3 now to 44.00)
44 red / loss / +39   (increase 1/3 looking for win after loss)
58 red / loss / -19 / (2 losses so decrease 2/3 to )
19 red / win  / +0  / (after win look for loss decrease 2/3)
6  red / loss / -6  / (after loss look for win increase 1/3)
8  red / win  / +2  / (after win look for loss decrease 2/3)
5 (assumes table min.) red / loss / -3

Hope that is more clear. I can tell you I have friends 
who tried to simulate it with negative result. But I 
have been playing it live forever and rarely have 
a losing session, and have never lost.
