10.3.33.6 Dual S-Curve

A Dual S-Curve is simply the sum of two S-Curves, and is specified by two parallel sets of S-Curve parameters. You can use a negative curve to make the series into a ‘hump’, or you can use two positive curves, with different Base Periods, to specify a series which rises, levels off, and then rises again.
