there is a peak for every sport especially for women although not all,
generally ages between 18-21 are the peak time to be competitive in ones career like in figure skating, gymnastics etc.
but there are those who matured late in the competitive area but got better as they get older or late bloomers
like Kostner, Akiko, Shizuka, Slutskaya
these imo, have proven themselves to have lasting careers
but Makarova ? , if pigs fly, she just got passed on WTT and is now being assigned for B competitions
