I am retired and have gone from workaholic to the laziest creature on the face of the earth. That is why I chose KO. But over time I have found some ways to improve its performance. One such improvement was extrapolated from the TKO spreadsheet downloaded from this Forum and from the Color of Blackjack.
First, I use an initial running count suggested by Fred Renzy several years ago in the Forum when I was just beginning. Instead of a KO IRC of -20, I begin my count at 80 (This makes 100 equivalent to 0 when using -20 as the IRC). So, my count begins at 80, my KO Key Count is 96, and my Pivot Point is 104, or just 4 (I drop the hundred when counting). Using this counting method, here is how it goes:
IRC = 80
True Key Count with 1 deck dealt = 89
True Key Count with 2 deck dealt = 92
True Key Count with 3 deck dealt = 95
True Key Count with 4 deck dealt = 98
True Key Count with 5 deck dealt = 101, or simply, 1
Contrariwise, KO Key Count with any # decks dealt = 96; so KO Key Count is only "True" at about 3 decks dealt.
True Pivot Point with 1 deck dealt = 4
True Pivot Point with 2 deck dealt = 4
True Pivot Point with 3 deck dealt = 4
True Pivot Point with 4 deck dealt = 4
True Pivot Point with 5 deck dealt = 4
KO Pivot Point with any # of decks dealt = 4; therefore, KO Pivot Point is always "True".
Here's how I use it:
1 deck dealt
78 wong out
79 to 88 = 1 unit
89 to 95 = 2 units
96 to 103 = 5 units
>103 = 10 units
2 decks dealt
83 wong out
84 to 91 = 1 unit
92 = 97 = 2 units
98 to 103 = 5 units
>103 = 10 units
3 decks dealt
88 wong out
89 to 94 = 1 unit
95=2 96=2 97=2 98=3 99=4 100=5 101=6 102=8 103=9 >103=10
4 decks dealt
93 wong out
94 to 97 = 1 unit
98=2 99=4 100=6 101=7 102=8 103=9 >103=10
5 decks dealt
98 wong out
99 to 100 = 1 unit
101=2 102=4 103=8 104=10
I haven't developed my betting progressions with any precision, just eye-balled them. The betting progression at 3 decks dealt is identical with the KO recommended progression except that it begins with 95 instead of 96. I haven't simmed it yet, so I don't know the exact gain (I told you I was lazy).
PS - Exit points begin at 78 and advance by five each deck dealt.
PSS - Key Counts begin at 89 and advance by three each deck dealt.
