What happened?!? The UDP numbers should have been at least a couple of HP greater than my last good run. I suspected that the pulley would not have any real power benefits, is this conclusive proof? I hope to do a back to back with pulleys someTime soon, but I wouldn't hold my breath over it. Other than that, the small power loss can be explained away as random variance.
