That's about right. The treble ribs I saw were 200-300mm long 
(8-12"), and about a 4M radius. Progressive radii, tighter in 
the treble, and all of them considerably tighter than is 
generally accepted as "standard" (whatever that is). Lessons 
learned a very long time ago, and forgotten. It's about time 
they surfaced again.
