On the surface Colin that would seem to be true, but i believe the 35" sub recommendation is based on the effect of skyglow and thus it is implied that you need many more short subs than longer subs to obtain the same amount of signal (assuming Gain was the same). When you reduce Gain as well it further compounds the need for more subs, at least that is my understanding of the chart.
