Lift is proportional to the square of speed and directly
proportional to the coefficient of lift (CL) CL is
typically close to linearly proportional to angle of attack
(AOA) over a range from about 0 to 15 or 16 degrees and then
departs from the linear relationship as it approaches CL max
which is at the stall AOA.

Yes, I know all that.

It's quite possible to be at low
speed, high AOA and find that increasing AOA more gives very
little extra lift as you approach stall.

But 80 knots isn't "at low speed". That's my point. And the idea of a
"flat lift curve" makes no sense to me. Except just above the stalling AOA,
every wing's AOA-to-CL graph looks pretty much the same.
