Observed number of zero crossings as a function of the predicted number of crossings for all 90 variables. The two g-mode hot subdwarf pulsators are shown as green triangles. The two dashed lines represent equality (bottom, in grey) and observed number of crossings equal to twice the number of predicted crossings (top, in red). Objects not included as rotational variables are shown as red squares. Objects with a high number of predicted crossings due to showing short periods often show less observed crossings because TESS data is not continuous, presenting a gap every ≃13 days when data was being transmitted to Earth.
