I do believe you, but it still sounds funny to the me. Kind of like how a golf ball flies farther because of its dimples. We know it does, just "doesn't seem right!" Very interesting stuff. Bottom line- a properly calibrated and operated flow bench does not lie. So this detrimental effect, just how significant is its penalty? I'm imagining it to be in the neighborhood of being almost an even wash; does this amount to a bunch of work for nothing? Stu Bryant
