It always used to be (DOWN to) 4% for CC (with a 60' crown 
radius, however that worked), then...  Somewhere during the 
soundboard crowning discussions on the list in the last few 
years, it was reported that CC boards were suddenly and 
mysteriously made with 4.5%MC. Then, somewhat later, 5%MC. I 
think I recall the last report as being at 5.5%MC. Wishful 
thinking aside, I somehow doubt that a reasonably functional 
CC board can be built at 5.5%, or even at 5% and survive for 
any length of time. Still, times change and the rules of 
physics do seem to be negotiable in marketing.

But then this is part of why I said I don't have a clue how to 
build a CC board.
