The solid line depicts hSARbr values calculated using all the users in our Twitter cohort. The dotted values show hSARbr for fixed cohort sizes of A. 100, B. 1000, C. 2000 D.4000 users. For a given cohort size, we create 50 cohorts, uniformly sampled from the available data, total cohort size permitting.
