At N0 hands, the standard deviation of the possible results is
equal
to the average result. So, for example, FPDW, since you know the
average result is always +.76%, therefore at N0 hands, the standard
deviation of possible results must be .76% . Assuming a normal
distribution (or "bell curve"), one can also make the following
statements: Plus or minus one standard deviation represents 68% of
the
possible results, or for FPDW: even to +1.52% is 68% of the
possible
results. Since plus or minus one standard deviation is 68%, 16% of
results must be lower and 16% of results must be higher, therefore
84%
of possible results must be greater than even and 16% must be less
than even or a loss.
NOTI,
My original posting had a math error, not a conceptual error.
So let me try to help out this way.
Assume: Normal Distribution
FPDW
ER = 100.76%
SD at NO = .76%
6SD = 99.73% of area under bell curve
Then visulize a normal (bell curve) centered on 100.76% with SD of
0.76%. Then at minus one SD the value would be 100%, while at plus
one SD the value would be 101.52% between 100% and 101.52% would be
68% of the area under the curve. Therefore 16% of the area under
the curve would be below 100% and 16% would be above 101.52%.
Therefore the total area under the curve above 100% (break even)
would be 84% (68% + 16% =84%).
What I was trying to say regarding the value of 102.28% should have
read 103.28% which is at three SD positive. And then I was trying
to say that 83.865% (100 -99.73)/2 = 0.135%= area under the tail
beyound 3SD, therefore 84.000-0.135 = 83.865% of the time your ER
would range from even to 103.28% ER
Did I get it correct that time?
