This is, by far, the most accurate ranking system so far in representing the true skill of a nation in any particular sport. that isn't too say that there isn't room for much improvement, and it certainly has its limitations. mathematicians and ranking experts could take this idea and improve on it significantly. it is also not meant as replacement for my suggestion of reducing the maximum size of national teams to similar sized regions (in terms of combined wealth and population). however, this system or an improved system like it could definitely be used with higher effectiveness in such a scenario.
*a nation's wealth and population is defined by Economic Determinant (e-determinant)
*the e-determinant is decided by population amount and gdp per capita amount, this is recalculated every decade (i would have preferred to use national wealth instead of gdp per capita, but such historic data is not easy, or even possible, to come by)
*final scores are adjusted depending on difference in e-determinant
*this causes mathematical problems for certain sports with poor scoring systems, therefore decreasing their accuracy compared to sports with better scoring systems. examples of poor systems: soccer football and ice hockey (severely limited scoring opportunities, too easy for defense), baseball (too much randomization in scoring opportunities, too easy for pitcher).
*certain regions in larger countries could potentially perform better or worse than the actual rating. the rating used for large countries is not an average (this would put large nations at a disadvantage because it would require an exponentially greater amount of upkeep), nor is it necessarily the representation of the best region within the country (this would put small nations at a disadvantage because it would require less upkeep for the larger nations).
*for now the regular Elo Rating system is used, this could change in the future
*the biggest enemy of any ranking system is lack of games played. when observers see an inconsistency in a result from a rating system they often blame it and not the true culprit. this is something to keep in mind when analyzing any such system. https://en.wikipedia.org/wiki/Law_of_large_numbers
RANKING: nations with at least 11 matches (if they have less than 30 the nation name is in Italic).
PROVISIONAL RATINGS: nations with 6-10 matches
ACTIVE & UNRATED: nations with 1-5 matches
OTHER SPORTS COMPLETED
- American Football (appears to be quite accurate, but it looks to me as Austria is overrated due to lack of games played. they should be in between Japan and Germany. This problem will resolve itself when more games are played).
- Australian Rules Football (this is looking pretty good, but South Africa and perhaps Britain should be ranked a bit higher in 2014).
- Circle Kabaddi
- International Rules Football
- Standard Kabaddi
*i'm working on data entry for several other sports. you may see statistics for them in nation profiles, keep in mind they will not be as accurate as possible until complete). i would like to complete basketball, rugby union, and water polo next.
