Well, at least we've got everyone on the same theme now. It's the
drag. Why don't you guys in Phoenix do a little testing and we'll do
the same here at M-ASA. I think we all agree that the heavier glider
has a significant drag advantage at high speed, and will gain
additional altitude. But how much, exactly?


So far I have not seen anyone consider the fact that, at the same
(high) speed, the unballasted glider has a significantly higher sink
rate at the start of the pull up. The initial conditions are not the
same.
