thanks Werner. Make sense now!
How does one interpolate between 2 sets of known data then? For example (see also attached) if one has data for a ratio b/d=0.1 and b/d=0.2 but one wants a Y value (K on the mcad sheet) for say b/d=0.164? Should one construct a "dummy" curve (spline) between thw 2 sets of data
basically - yes. You are asking for a 2-dimensional interplolation. Guess the attached sheet should help.
