World champion 1983: Francis ("Daley") Thompson, 8666 points
But according to the points calculator on
https://en.wikipedia.org/wiki/Decathlon and on this site his results give
10,60+07/7,88+16/15,35/2,03/48,12/14,37+21/44,46/5,10/65,24/4:29,72
952 /1030 /811 /831/903 /927 /756 /941 /817 /746 =
8714 points
If subtracting (7+16+21=) 44 points (some sort of correction?) we
get 8670 points,
What kind of points calculator did they use back in 1983 ?
