Torygraph Exclusive: Six Nations will use bonus points on permanent basis after last year's success sees trial period abandoned.
It looks like I am going to have to wrap my head around it then. Herewith the skinny from the rules page of the Six Nations site. Rule 3 is what we are interested in.
1. The NatWest 6 Nations Championship is contested each season over seven weekends during February, March and sometimes April by the international sides of France, England, Ireland, Italy, Scotland and Wales.
2. Each team plays the other five once per season with home advantage in alternate seasons (eg England hosted France in 2003, and so France host England in 2004), giving a total of 15 matches per Championship.
3. The following points will be awarded based on the results of each Match (such points to be referred to as "Match Points" to distinguish them from points scored on the field of play):
(i) The Union that wins the Match shall be awarded four Match Points or (if it scores four tries or more in the process) five Match Points.
(ii) The Union that loses the Match shall be awarded no Match Points or (if it scores four tries or more in the process or loses by a margin of seven points or fewer) one Match Point or (if it scores four tries or more in the process and loses by a margin of seven points or fewer) two Match Points.
(iii) Unions that draw a Match shall each be awarded two Match Points and any of them that scores four tries or more in the process shall be awarded a further one Match Point.
(iv) A Union that wins all five of its Matches (a "Grand Slam") shall be awarded a further three Match Points.
4. If in winning the Championship a team also wins all of their five matches, they are given the title of 'Grand Slam' winner.
5. There is also the title of 'Triple Crown' competed for each season, which is awarded if a team from the 4 Home Unions (England, Ireland, Scotland, and Wales) beats each of the other 3 Home Unions.
