Re: uncurve/curve comparison on Loris' website

My mistake then.  It sounds like you have been able to calibrate a curve that works well for you.

Yes,  you did misunderstand completely.  That was in a different 
thread altogether;  I was discussing curves for gum in general, and 
to illustrate a point, I was describing some curves and charts people 
have sent to me over time as examples of "good" gum curves, that fit 
that description.  They were generated, actually, from the PDN system 
(although I didn't mention that because I didn't think it was germane 
to the discussion).   But no, I wasn't describing any curve of my 
own, nor do my curves fit that description.
