Evolutionary tracks of the 0.8 (left panel), 1.0 (middle panel), and 2.0 M_⊙ (right panel) stars with chemical composition [X = 0.703, Y = 0.280, Z = 0.017] calculated with the SFCT forced to include the strict pressure balance at the surface of convective elements (dotted red line). The corresponding models with the MLT with mixing length parameter Λ_m = 1.68 (black line) are also shown for comparison. The agreement is beyond any reasonable expectation. The MLT is clearly a particular case of the SFCT.
