You try it I know what will happen. You will end up with a broken hand if there are enough people pulling on the two ends of the rope.
I ran another test of with the weight. Free the weight weighed 10.63 lbs and when wrapped around the diablo 10.56 lbs. This time it was 0.07 lbs less. Now if the friction of the diablo makes a difference why can't the scale detect it?
