Two different springs are used so that the advance "curve" more closely
resemles just that a curve.  If two identical springs were used the curve
would be linear.  With two different springs, the curve, as plotted on a
graph, is comprised of two strainght lines.  The first is the steepest.  And
the second is a little less steep.  Once the maximum advance has been
achieved, a third line can be added to the graph which runs horizontially.
 Any good automotive book covering ignition systems will illustrate a typical
advance curve.  You could also plot your own using a timing light with a dial
which allows you to zero out the light.
