Earlier in 1984 the IAAF had updated its decathlon scoring tables; the tables set in 1962 (with effect from 1964) would be replaced on 1 April 1985.[2] The world record performance at the changeover date would be recalculated using the new tables and become the new world record.[2] In the event that another performance had a lower total on the 1962 tables but a higher one on the 1984 tables, it would not supersede the pre-existing record.[2]
These were the standing world and Olympic records (in points) prior to the 1984 Summer Olympics:
| Record | 1962 tables | 1984 tables | Athlete | Venue | Date | |
|---|---|---|---|---|---|---|
| World Record | 8798 | 8832 | Jürgen Hingsen | Mannheim (FRG) | June 9, 1984 | |
| Olympic Record | 8618/8617 | 8634 |  Bruce Jenner | Montreal (CAN) | July 30, 1976 |
Daley Thompson's time in the Olympic 110mH was initially recorded as 14.34, on which basis he started the final 1500m needing 4:34.8 to beat Hingsen's world record, or 4:34.9 to equal it. After slowing at the end to enjoy his triumph, he finished in 4:35.0, giving a points total of 8797, one below the world record (still a new Olympic record).[3] The time was over 14 seconds outside his personal best.[4] Under the 1984 tables (taking effect in 1985) Thompson's 8797 scored 8846, whereas Hingsen's 8798 was only 8832.[2] Nevertheless, Hingsen retained the record under the IAAF's grandfather rule.[2]
In 1986, the IAAF re-examined the photo finish of Thompson's Olympic 110mH, found it was one-thousandth of a second faster than initially thought, and rounded his time down from 14.34 to 14.33.[2] [5] This gave him one extra point, thereby retrospectively equalling Hingsen's 8798 under the 1962 tables, and scoring 8847 on the 1984 tables.[2] The IAAF ruled on 15 July 1986 that Thompson was co-holder of the world record from 9 August 1984 until 1 April 1985, and sole holder thereafter.[2]
