Steve, I once ran a scenario where ten 36" ducts ran parallel, 18" below the ceiling deflectors, with a 1" gap between each. Make the ducts 47" if you like and the gaps 3" if you like. Meets the rule but you essentially would have 30-50 feet of solid with waterfalls every three or four feet. I can't remember whether it was Phil or Roland that wrote the informal response to my question, whomever agreed that it met the standard. Fixing this little loophole?
