Comparison of Exponential and Logarithmic
Curves
Exponential Curves and Logarithmic Curves have
similar shapes. They are different, however, as the
following diagram illustrates:
Factor +40
CURVE: LOG
Y
X
Factor +40
CURVE: EXP
Y
X
X Axis = random choice with equal probability between min and max. Y Axis = the Pool.
This characteristic can be used to even more finely tune
the effect you are trying to achieve. For example, the
top and bottom curves in both the Log and Exp
diagrams (Factor 40 and -40) above are shown together
below:
Factor +20
Factor +10
Factor 0
Factor -10
Factor -20
Factor -40
Factor +20
Factor +10
Factor 0
Factor -10
Factor -20
Factor -40
