For the Cat IV glider plans Ive seen, how come none of them aren't
even close to the max wing area of 100 sq. in? Is it because its harder
to launch as high? Weight?

Precisely. 100 square inches would be a mammoth glider for cat IV.
The only way to get any altitude would be to make it brick heavy, or
discus launch it. Problem is 100 squares is a bit small for effective
discus launching.

If you have never flown any Cat IV HLG a good place to start is a
Sweepette 19 built light (say 20 grams). After you get the hang of
that go to a Supersweeep 22 or any of the other popular Cat IV
designs. Remember you can practice fly outside on calm evenings,
especially with a Sweepette 19.
