The point is to sell hardware and not to know which program is best. If a single processor is going to win multi processor programs then the people who sell computers with more than one processor are going to lose so they are not going to let one processor program to prove that it is better. 2)When the quality is similiar more processors are better and the quality in the top programs is similiar(see the ssdf list).
