Stellar accretion rate Ṁacc vs. gas disc mass Mdisc shown for all disc wind scenarios (see Table 1) with a weak FUV field strength distribution. Evolution tracks of individual systems, coloured by ℱFUV, and snapshots at 2 Myr (green circles and 3 Myr (orange circles are displayed. Tracks of exemplary cases are highlighted with black dashed and dotted lines. We show the detailed evolution of those exemplary discs in Figs. 3 and 4. We compare our simulations with observed populations in Lupus and Chamaeleon I. Observational dust disc masses and stellar accretion rates are taken from Manara et al. (2019) and dust masses are converted to gas masses by assuming the standard dust-to-gas ratio of 0.01. Triangles denote upper limits on disc mass. Lines of constant Mdisc/Ṁacc are shown for 0.1, 1 and 10 Myr (thin dotted lines).
