Rib Crowned and Supported - ribs shaped to relatively small radii, board
ribbed at relatively high MC, panel under little compression and has no
significant crown-supporting function.

Rib Crowned - ribs shaped to relatively large radius (commonly 60-foot),
board ribbed at moderate to low MC, panel compression in part supports
crown.

Rib crowned is a bit of a hybrid - somewhere between CC and RC&S. There
really is a continuum between the two extremes of CC and RC&S.
