More competitive field. More consistent ladies with solid 3-3s and 7 triples programs. Most of these ladies weren't exactly bombing left and right after their worlds medal. Radionova for example, the season after wasn't bad. Despite a major grow spurt she medaled at all her events but worlds, the only one who beat Medvedeva that season (she could have beat her twice if things were done in the right way imo). Worlds had the most competitive field till then. Top 7 was above 200 points, which was unprecedented. In 2015, just the 1st was above 200. In fact Radionova did better than when she won a worlds medal. Same for Pogo (Though she had a disastrous FS at worlds. But it was more a mental thing than anything else) or Wagner. Sure the next season was less good for Radionova but not a total bombing. Things just got more difficult in Russia.What changed in 2015?
Julia Lipnitskaia won silver at 2014 worlds and was never heard of again. Elizaveta Tuktamysheva won Worlds in 2015 and that was it. Elena Radionova was one and done. Wagner, Pogoryllia, Daleman, Higuchi -- the same number of world medals as Zagitova, one. Yet these skaters competed under the same scoring system at Kim, Asada and Kostner.
