Discretization of MOS based on the Table B.1/G.107 – Provisional guide for the relation between R-value and user satisfaction

=IF(“cellval”<2.58,1,IF(“cellval”<3.1,2,IF(“cellval”<3.6,3,IF(“cellval”<4.03,4,IF(“cellval”>4.34,5))))). Replace “cellval” with MOS ratings obtained using the ITU-T G.107 recommendation (2009 tested).
