Great Math! But I think we are baseing this on the
wrong constant. All of these base the constant on airspeed.
I am not a mathematition (I can't even spell it) but
if we base it on sink rate it should be alot more
obvious. After all thats exactly why we carry water
ballast in the first place, to increase speed for the
same amount of altitude loss right? So if your going
10 knots faster in the ballasted glider and at the
same sink rate as the unballasted glider. You will
gain more in pullup, right?
