Blaine value vs position parameter

The slope "m" of the Rosin Rammler distribution is the first way to characterise the fineness of a powder. The second way to characterise the fineness of a powder is the "position parameter" of the Rosin Rammler distribution, which corresponds to the intercept on the x axis of the distribution, i.e. when ln(ln(100/Residue)) = 0.
