The calculation of points in the all-around athletics competition seems complicated, and it seems that there is a scoring system for each event. However, if you look at each item carefully, it is not the same as the prevailing individual scoring. If it's a big year, another system of scoring is even more important. Several scoring systems are stacked on top of each other, making it confusing.
At the beginning of the all-around event, there was already a standardized scoring design, otherwise the competition would not have been possible. The men's decathlon is not the same as the women's heptathlon. In short, they are all calculated using advanced mathematics.
Because of Zheng Nina's relationship, this article will briefly talk about the women's heptathlon.
Dr. Karl Ulbrich (born 1905, died 1987), the first geodetic surveyor in Austria to receive a doctorate in technical sciences, was the architect of the heptathlon score.
He was one of the first to devise three sets of formulas for the calculation of scores for each achievement in the all-around running, long jump and throwing events. And set the benchmark. For example, the high jump of 1.82 meters is set to 1000 points, and 1.74 meters is set to 900 points... 0.75 meters is set as 0 points. How to calculate the increment of various variables in the middle is not something that can be explained by this mathematical slag.
Also, for the time being, don't worry about the player's results, what if it's too strong to exceed the formula table. Taking the women's high jump as an example, the highest score score has been designed to 2.19 meters, a height that contemporary female athletes cannot imagine.
Taking Zheng Ninali's winning results in this national championship as an example, her seven events are: 100m hurdles, 13.74 seconds, 1015 points; High jump 1.80,978 points; Shot Put 13m 21,741 points; 200m 24.87,899 mins; Long Jump 5m: 97,840 points; Javelin 45m 66,776 points; 800m 2:29.64,697.
The total score is 5946 points.
But what is the matter with this 5946 points, and the final converted score is 1053 points. That's another more powerful scoring system for athletics. It was designed by Borgidar Spiriev, a Bulgarian statistician and hydrogeological engineer.
He himself is a Bulgarian national champion in the 400m hurdles and has participated in the World Games. After moving to Hungary in 1961, he developed a Hungarian-style track and field scoreboard, with a conversion score for each track and field event, in order to measure the performance of athletes in each event more comprehensively, and also to lay the data foundation for the points ranking system that emerged in the Internet age.
This brain-burning statistical model soon became the official scoring method of the IAAF (now the World Athletics Federation).
After the advent of the Internet age, he and his son founded the famous "All Athletics" website. The big data ranking and scoring system currently adopted by the World Athletics Federation is based on the "All Athletics" website.
After Spiriev's death in 2010, the all-athletics website was closed, but its unique scoring and ranking system was completely inherited from the World Athletics website.
Taking individual events as an example, Spiriev's scoring system is generally higher than that of the all-around scoring and should not be confused. Taking the women's high jump as an example, 1.80 meters can reach 1,000 points in the all-around and 1,023 points in individual events.
Over the years, there have been fine-tuning of the all-round scoring method, so I won't say much about it here.
