Notice that, from the point of view of griefing factor analysis, it is immaterial whether or not any hash in a given epoch was justified or finalized. The Casper mechanism only pays attention to finalization in order to calculate $DF(D, e, LFE)$, the penalty scaling factor. This value scales penalties evenly for all participants, so it does not affect griefing factors.
