Just a quick go online (mainly to see if I really did appear in the “whos online” bit of www.nintendowifi.co.uk – I didn’t), and played a Rivals game.
I don’t know how it calculates the “rival-ity” of the people you play, but all three had 170+ wins, and less than 10 losses each. Rubbish. As in, I was. Scraped joint second, somehow, but only through luck in getting the right weapons at the right times. Pah.
