From there I know that, as user1269942's answer suggests, you start with the max cell and work your way down the value list, adding until you hit the 80% mark - preferably within some fudge factor in case a group of cells with the same value pushes you over the edge. And I don't know an existing tool/method to do that. If this script works, it's got my vote. | |
