Has anyone come across 20% rule on the new 17th ed boards

Is it on the whole of the board. or each sub section, ie 20% fist rcd, 20% second rcd ect. ect.

cheers....

ahhhhhh! now i understand onit is on about spare capicity .as far as im aware there is no requirement to leave any space spare. if you fill one board then add another and another.........
we tend to go for 25% spare the current db im doing has 50% spare ,but thats the client s choice ! (24 triple pole ways)
