Difference in T_max between the cadence simulations (Sect. 5.1) and reference sample (ΔT_max) as a function of the phase of the first observation. The simulations are split in three groups according to the cadence (cad) range: 2 < cad < 5 days (purple crosses), 5 < cad < 8 days (pink circles), and 8 < cad < 10 days (gold squares). T_max is shown as a vertical dashed line. Independent of the cadence, the scatter in ΔT_max starts rapidly increasing for the first observations with phases of ≳ − 5 days.
