What about the L/D polar being skewed to the right to the benefit of the
higher
wing loaded vehicle. At VNE the heavier a/p is cleaner and will glide
farther.
If both a/p's pull up together, the cleaner a/p runs out of energy last. It
looks to me like
heavier climbs further.....

Since mass is a constant factor on both sides of the equation, it
cancels out. Therefore there should theoretically be negligible difference
in the pullup altitude gained between the ballasted and unballasted
cases.True except for two things:The ballasted glider has more induced
dragwhile at the same airspeed as the unballasted oneThe ballasted glider
also has a higher stall speedSo the unballasted glider will go higherMark
