The ranking doesn’t take in account the level of the teams which is the main criterion I retain for every match because the World Rugby’s principle is simple : the winner gains some points, the loser loses them.
It doesn’t take into consideration the games against the countries which aren't members of World Rugby, even when the tournament is organized by a World Rugby affiliated federation, nor does it the matches against the teams I called special (Nomads...), as well as those against ranked teams having a difference of more or less than 10 points in a 0 to 100 ranking.
Finally, any introduction in the World Rugby’s rankings is arbitrarily fixed, no matter what the previous results of the countries are.
For every international match, I've attributed since 1982 for women, points to every country as a sum of several elements.
I mainly take into account the match level (generally the points average of the 2 teams before the match, with minima) and the kind of result (win, draw, defeat or forfeit).
But I also count the match venue (at home according to the opponent from the continent or not, in an other country of its own continent, on neutral ground, in a country of the continent of its opponent, away according to the opponent), the number of scored points and the difference between the number of scored points and the number of scored points by the opponent.
Finally, I add a bonus for WRC.
There are a few exceptions in this method, in particular when countries play A, B , Emerging, Amateur, Junior, Student, Army, Police or Services teams, even provinces or clubs in official competitions.
In an official competition too, results of A, B, Emerging or Juniors teams can make the said country points marginally move, with a specific calculation.
Finally, matches results with « special » teams (Nomads, Caribbean Select) are counted and these teams classified apart.
The points number after the match is equal to the sum of 10% of the match points and 90 % of the points number before the match (possibly 20 % and 80 % for women's teams playing very few or in the World Cup). This method allows to take less into account surprises and requires regularity in performance to progress. Besides, it favors countries the level of which improves by often playing to the detriment of those who play few, the number moreover decreasing in 2% each year.
To present my rankings on October 2009, I worked more than 2 years to compile men's data and one year to compile women's data from all the important sites (thanks to them). And also to realize multiple tests which allowed me to validate the method.
