Hey Dale,
I know you were just shooting figures off the top of your head, but just for the record, it would be 4mm deflection on a 15" radius over 15". Hardly scant, IMHO but God bless your soul. I'm all for a healthy dose of crown up there and I have been, admittedly, way too conservative.
Best,

I crown these ribs as tight as 15 ft but even so on a 15 inch rib were only talking scant MM or 2. But I like having something to push against that resembles real crown.
Makes sense?
Dale
