It's actually 3 worlds, (2010 silver, 2011 silver, 2013 gold). I'm actually more impressed by Yuna's post Vancouver career than before. She had a life outside of FS after the Olympics and to accomplish what she did after winning her dream gold is pretty special. And the manner she finished off her skating career with 4 clean programs at her final two two major competitions is just icing on the cake.
Oh yeah, I guess I was thinking during the previous quad (2011-2014). But yes, after Vancouver she won three World medals.
FWIW:
World medals
2 golds (2009, 2013)
2 silver (2010, 2011)
2 bronze (2007, 2008)
Olympic medals
1 gold (2010)
1 silver (2014)
GPF medals
3 gold (2007,2008, 2010)
1 silver (2009)
GP medals
7 gold
1 bronze
4CC medal
1 gold.
Really not a bad haul for Adelina to emulate.
