8-4-7-2, that's how much the sheet de-intersected, not how much i wanted it to, a poly somehow duplicated a whole section of my level into a builder brush. Well i wanteed to deintersect the brush so i wouldn't get all the funky stuff because i didn't want any leaks in the level, since i would deintersect, the face would make a perfect seal without any excess giving a clean split. I've used other portal based editors and well it never made a diference if there were splits in the portal, hell in the game i've never seen a hom effect unless the rooms shell was open
