Detected fraction of RV-variable simulated binaries with variability probability P(χ²) > 0.5 among all observable CMC binaries, shown as a function of orbital period (left), mass ratio (center left), number of epochs (center right), and stellar evolution stage of the primary (right). Confidence intervals, calculated by varying the probability threshold between 0.4 and 0.6 and adding Poisson noise uncertainties in quadrature, are shown as shaded regions.
