Suddenly, only data-based matches can explain strength.

For example, running, swimming, hurdles, how many seconds can you run in the stipulated distance. It is real that you can break the world record.
But like similar events such as diving, table tennis, badminton, volleyball, basketball, there is no standard data. In other words, if A's strength is 95 points, A's opponents are all 85 points, A won the gold medal, but A only participated in one Olympics and retired.
The young generation B's strength was 85 points, but his opponent's strength was only 75 points, B also won the gold medal, and he won several medals every year.
So, can you explain that B's strength is stronger than A? Of course not.
Even for swimming, running, hurdles, diving, table tennis, badminton, volleyball, basketball, there is a standard number where it can be broken, such as Liu's 12.88 seconds and Pan breaking the 40-year record. This kind of thing can be seen at a glance.
