Rankings for individual competitors and for national teams look similar and operate on entirely different principles. The difference comes from what each is trying to describe.
Individual rankings are accumulations
An individual ranking typically sums points earned at a set number of events within a period, so the total describes what the competitor achieved.
Points depend on how far the competitor progressed and on the tier of the event, not on who they beat along the way.
The table is therefore a record of accumulated achievement, which is why a competitor who plays more events can rank above one who plays fewer.
Team rankings are estimates
A national team ranking is usually a rating that estimates current strength, updated after each match according to result and opponent quality.
Playing more matches does not raise the rating by itself, because the rating is an average-like quantity rather than a running total.
A team can therefore improve its position by playing rarely and winning, which is the opposite of how an individual ranking behaves. A run of friendlies against weak opposition can even reduce a strong team's rating.
Why the difference exists
Individual competitors control their schedules and enter events voluntarily, so a ranking based on achievement rewards the activity the tour needs.
National teams play a fixture list largely set by qualification and confederation calendars, so rewarding volume would rank teams by their calendar rather than their quality.
The two designs also serve different purposes, since individual rankings determine entry and seeding while team rankings mainly determine draw pots.
What each system fails to capture
Accumulation rankings understate a competitor who has been absent, because points are missing rather than performance being poor.
Rating systems understate teams in isolated regions, since a team can only demonstrate strength against opponents it actually plays.
Neither problem is solvable within the system's own logic, which is why both are supplemented by discretionary adjustments at the margins, usually in the form of wildcards or seeding committees.
Where the two converge
Some sports now run both, using an accumulation ranking for entry and a rating for seeding, on the basis that the two questions are genuinely different.
The separation is honest about what each measures, rather than forcing one number to serve purposes it was never designed for.
Reading a table therefore requires knowing which type it is, because the same movement means very different things in each.
