Wales rise to third in rankings
Wales and South Africa move up a couple of places in the World Rugby Rankings after completing series victories over Argentina and England respectively.
Men’s and Women's World Rugby Rankings are calculated using a 'Points Exchange' system, where sides gain or lose points based on the match result. Other criteria include the relative strength of each team, the margin of victory, and an allowance for home advantage.Full Explanation
All member countries have a rating, typically between 0 and 100. The top side in the world will normally have a rating above 90. Any match that is not a full international between two member countries does not count at all.
Points are doubled during the World Cup Finals to recognise the importance of this event, but all other international matches, friendly or competitive, are treated the same across the world.
