Median evolution of the M₂₀₀ value for the 214 FoF groups in our sample, normalised to its value at z = 0.5. The grey shaded regions represent error bars derived from bootstrap resampling. The orange vertical lines indicate the median ongoing (solid line) and outgoing (dashed line) crossing times of R₂₀₀ for green BSs. The green solid vertical line represents the median group ongoing time for green RINs. The grey dashed line marks z = 0. The orange shaded region denotes the diving stage for green BSs, while the green shaded area highlights the diving stage for green RINs.
