Kostner is only getting better in what aspect? Artistically - maybe, but definitely not technically. Ando is slowly developing her artistic ability (or rather ability to evoke emotion), and I think she hasn't reached her true potential in that department yet.
What Ando has that Kostner lacks (besides this season) is consistency. Last year, I believed all her LPs were skated cleanly.
Remember, Ando won the bronze in a strong ladies' field in 2009, and placed 5th at the Winter Olympics. If it had to do with timing, Ando wouldn't have achieved such admirable achievements. Kostner was able to win despite lackluster technical content is because of the TIMING - the field was so weak this year, you didn't need a 3-3 to medal.
Sigh 5 triple program, no lutz and you get a world championship. the standard for women have dropped a lot since the days of midori, yuka and michelle, by a mile
