Is table HRR_DASHBOARDS only supposed to include data for reviewees?

I'm confused about data I'm seeing in HRR_DASHBOARDS.  Can someone confirm if the data in it should only be for meeting reviewees (population)?  The bulk of the columns are related to the various ratings someone could be given, so it was my assumption that only reviewees would exist in the table, but I'm seeing non-reviewees in it, as well.
