Numerous previous studies have shown that one-zero sampling in direct observation systematically overestimates behavioral durations. A post hoc correction procedure has been proposed and demonstrated to be capable of removing most of the systematic errors found in one-zero duration estimates. However, the remaining errors for some individual observation sessions can still be quite substantial in practical terms. In this paper, the condition under which the post hoc correction procedure will produce results with negligible systematic errors in one-zero duration estimates is identified.
