Thanks very much for the suggestions, Richard. Iʻm working through them
now and will let you know if I can manage to wring a decent print out of
the profile. You are right about that head-scratching thing.
I have not needed to build QTR curves for a couple of years — until the MIS Eboni-6 formula changed. I was not aware of the QTR correction curve tool. Thanks for that link! I downloaded it and it looks like it will make curve building go more smoothly.
