I meant it all along but perhaps it is hard to do it on the fly. Ther
rules seem to be as follows:

1) Both outside (both positive), choose a smaller value
2) Both inside (both negative), choose a smaller value as in (-5 < -4)
not by absolute value
3) one inside one outside, choose a smaller value as in (-3 < 2) not
by absolute value

I.e. always choose a smaller value combining two contours so it seems
