  In a recent paper (Kovacs 2018) we examined the incidence rate of the
modulated RR Lyrae stars by using the data from Campaigns 01 - 04 of the Kepler
K2 mission. We found an observed rate of ~90%, implying near 100% underlying
rate, after correcting for detection bias due to observational noise. In this
work we extend the sample to Campaign 08 and check the reliability of our
earlier estimate. We get the same high rate, stressing the importance of full
time series modelling (including systematics) in searching for shallow signals
in the presence of large amplitude variabilities.
