"When I look at the two (L,Aubqe) plots I have, the first thing I see is an empty vertical gap about 10 units wide whose right edge is near the L-mean. The distribution on the left of the gap looks linear, but the distribution on the right looks more like a quadratic tipped on its side, as in L = a + b*(Aubqe - c)^2. Does anyting like that show up anywhere else?"
Question noted. Will let you know as I "ring the changes" for the linearity checks.
