On a technical note......and you can research this cause,well its fun.
Traditionally "scotia" has been the go-to mould under nosers......But somehwere 'round the late 80's it wasn't being stocked anymore.Which mesh's in with the advent of "Box stores".After that time "cove" became the default pc.
The differences may seem like splitting hairs?.....which I can put up a very compelling argument that it isn't(splitt'n hairs).A cove is a constant radius,with generally the same amt. of fillet(little sq section),top and bttm...........Scotia on the other hand,at least WRT the pce under a noser.....Has two noticibly different fillets.The one that we use on top is much wider.The point is visual,you're looking "down" at the tread.And just like scotia is correct under window sills,its correct here under noser cause this wider top section spaces the radius'd or curved section...lower.Uhhh,that would be so we can see it.Scotia also is sposed to be a multi radii on its cruved part.Tighter at top,flattening as it gracefully curves lower.
Scotia,properly prepared,somewhere about 5/8" thick and easily 7/8" tall.Its a "forgotten" profile in the,slam-bam-dooh-dah architectural times we live in.BW
Those who say it cannot be done shouldn't interrupt the people doing it.
