The good, the bad and the mirrors

In the women’s section of the Tromso Olympiad , the following teams are the over-achievers of the tournament. They have a final ranking ( in bold figures ) at least 20 places above their seeding ranking ( calculated according to the ELO ratings of the team members )

Tajikistan                   50                      83

 Zambia                      77                    109

 Paraguay                    49                     75

 These teams performed just on par :

 Bulgaria                        14

 New Zealand                 73

 Costa Rica                    86

   Other interesting figures also come out . Observe these three pairs of teams:

 Russia (1,2 ) ; China (2,1 )

 Poland ( 7,8 ) ; USA ( 8,7 )

 Armenia ( 5,10) ; India ( 10,5 )

 I call them “mirror teams”, a term with a curiosity value only.
