The StkUltra Odds Line
StkUltra can produce a very accurate odds line. The calculations strictly
adhere to rules of statistical probability. StkUltra can force the odds
to be exactly accurate by spreading the odds and testing the spreaded
odds against the past history.
The StkUltra Calculated Probability report shows the results of the
spreaded odds test. Predicted wins are calculated by dividing the number of
horses whose odds are set at each odds number by that odds number plus 1.
The accumulated deviation shows how accurate were the odds over
the spread of the lower twenty numbers. Accumulated deviation of zero means
the odds were exactly correct through the column in which the zero appears.
The accumulated deviation should be zero or positive through half the odds
numbers going from 1 to 20. The last deviation number under column 20
should be near zero or no more negative than a tenth of the number of races
in the sample.
