In tables of reverse busts, one sometimes finds what seems like an unreasonable number of reverse busts (as, in this table, for UN7E/7). This is generally caused by a discrepancy between the call actually sent by the listed station and the one recorded as being sent in at least some QSOs in the station's log.
