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?
a 10 lb weight will weigh 10 lbs regardless of whether a diabolo is used or not.
the question is without the use of a diabolo, how much clamping pressure does the gripper need to apply to prevent the string from slipping through the jaws? and how much clamping pressure does the gripper need to apply to the string when a diabolo is used? your test can not possibly measure that.
