ERRATA:
2021-02, Revision to Section 4a: There were 38 subjects in this test. Subjects were tested 4 at a time in the EER at 4 separate seats near the center of the room. The subject seat number can be found by modular division of the subject number. 8 groups were full, and 2 groups only had 3 subjects in which cases seat 4 was empty. Accordingly, there was no subject number 20 or 28.
