Evolution of the difference between the evidence of the two- planet model and the zero-planet model as a function of the number of data points (dark blue solid line and symbols, corresponding to the lower X-axis) and against the time from the first observation (light blue dotted line and symbols, corresponding to the upper X-axis). The regimes of Δ ln 𝒵 < 6 (or BF = 400) and Δ ln 𝒵 < 0 (BF = 1) are shown as dark and gray shaded regions, respectively.
