looking here in iaaf world record progressions book for kondrateyeva's 10.87 on page 249 :http://iaaf-ebooks.s3.amazonaws.com/2015/Progression-of-IAAF-World-Records-2015/index.htm
Three types of timing device - hand timing, automatic timing and a
photo-electric cell device were in operation at this meeting. The automatic timing was not used as the film did not
develop properly, and so times were taken from the photo electric cell device. As IAAF rules required a photofinish
to be submitted, the Soviet federation did not submit the mark for approval as there was no photo (a similar
occurrence the following year did not prevent the approval of Sebastian Coe’s 1:41.73 WR).
description relevant to coe's time on page 58
Coe 1:41.73 (the photo-finish equipment failed to function
properly, and the time was determined by analysis of 3 photo-cells positioned at 3 heights at the finish. Hand
timing: 1:41.6 - 1:41.6 - 1:41.7!)
photo-electric cell clockings were NOT & never have been acceptable for auto-times
bottom line is that coe's time shoud never have been submitted as a fully auto-time & shouda been listed as a hand-time
whether his hand-time was acceptable for a wr is controversial
after 1st january '81, iaaf requested auto-timings for all wrs upto/including 10k
the next wr to test this was rono's 13'06.20 in late-'81 on page 88 :
Rono 13:06.20 (Hand timing; all 3 watches 13:05.4, but for the first
time, they were officially only an aid in the event of automatic timing failure)
the hand-timing in rono's wr was hugely quicker than auto-time by 0.8s !!! & it wouda been a travesty if 13'05.4 had been accepted instead of 13'06.2 if auto-timing had been broken
whether rono's hand-time wouda been accepted in case of auto-time break-down is unclear & hence by implication coe's hand-timed run
