Thanks, BM,
I’m just now seeing your suggestion to implement the rounding.
However, it doesn’t quite match my vision of how the curve should look. By now, I’ve come to believe that if something can’t be done in MOI, it probably can’t be done in real life either. So it’s likely that my mind and imagination are what aren’t quite right or can’t be reconciled with reality.
Thank you very much again for your admirable effort. No idea how I could make up for it...cheers...
