+1 It doesn't make any sense. We know that if the gap is the same that you would extract the same amount of sugar, creating your efficiency. It is possible that your faster milling can up your points. However, only if the gap changes with how fast you mill. Maybe that's a Corona mill thing. You've said that it works for you, which I believe. Now you just need to figure out how it works.
