Ratio of evolutionary and spectroscopic masses vs. spectroscopic masses for the sample stars. The former is inferred from the Geneva and Bonn tracks with rotation. The dashed line is the one to one relation. Same symbols and colour coding as in Fig. 8. The most outstanding outliers common to both grids are denoted by numbers: No. 1 – CP−47 4551; No. 2 – HD 169582; No. 3 – HD 148937; No. 4 – HD 64568; No. 5 – HD 207198; No. 6 – CPD−58 2620.
