WebRDF = ADF * Q† (9a) Note the factor Q† should reflect the corrected RDF value. Of course the original definitions of RDF (and thus equation 9a) did not account for the ‘[1 / (1 – .005161 * RE)]’ correction term. It was noted that Balling first pro-posed calculating the ratio of RDF/ADF20 and it is termed ‘Balling’s shorter formula’.
