Time-delays relative uncertainties for the object presented in this work (colored dots) and already available in the literature (gray dots) (see Table 3 of Millon et al. 2020, for a list of published time delays). For quadruply imaged quasars, the combined uncertainties between all three independent time delays, corresponding to the minimal uncertainties achievable on H₀, are shown under the assumption that the time-delay errors remain the dominant source of uncertainties. The outer light blue circle corresponds to a precision better than 15%. The inner blue circle corresponds to the target region with precision better than 5%, corresponding to the threshold at which the time-delay errors become smaller than other sources of errors in the inference of H₀.
