Bob,am sure you know this but it's one of those things about millwork.....
Nominal vs net measure on crown(and other trim millwork).A pce of 4" crown(nominal) will usually run 3 5/8" or so,net.Same for other sizes.
Best thing is to cut 4-6" long,"try" pcs.We have an inventory of a bunch of different pcs/profiles.It really is a help when splitting hairs on assemblies......and during the planning phase of builds.Especially with crown,as in some cases(ha) you can change the bed angle to create different aspects/clearances.
Be careful with that because....what's started(angle of repose)is going to have to "end" somewhere.Use it where the crown obviously dosen't have to match anything.And we're only talking a few degrees,but sometimes thats all it takes.Good luck.
Those who say it cannot be done shouldn't interrupt the people doing it.
