Hi Pete,

I was the one who pointed out that the formula as originally posted was not correct. I'm not sure the above fixes fix it either, but I could be wrong. I haven't studied it.

You're right. They don't fix it. It's still incorrect.

There are some points concerning to your formula:
I tried what you say but I still don't know how
to get the insurance index. Is there anything wrong
with the data below? How would you proceed to get
it?

1) Full Deck

N = 52
N [i] = {4, 4, 4, 4, 4, 4, 4, 4, 4, 16}
C [i] = {-1, 1, 1, 1, 1, 1, 0, 0, 0, -1} // Hi-Lo
E [i] = {1.81 1.81 1.81 1.81 1.81 1.81 1.81 1.81 1.81 -4.07} // Insurance EORs 


tc (E)     =   -0.000769

tc (C)     =    0.000000

dot (C, E) =   94.080000

dot (C, C) =   40.000000

b          =    2.352000

mu         =   -0.000769

2) Ace Removed

N = 51

N [i] = {3, 4, 4, 4, 4, 4, 4, 4, 4, 16}

tc (E)     =    0.034706

tc (C)     =   -0.019608

dot (C, E) =   95.785882

dot (C, C) =   39.058824

b          =    2.452349

mu         =    0.082791

Thanks you in advance,

Cacarulo
