No citations were made. Based on my experience when I used a conical burr grinder I noticed the flow of espresso remained the same for weeks without having to make grind adjustments. It seemed that the grind must be shaped different enough whereby they acted as they adhered to each other like a puzzle vs flat burr grinds.
