No, it was mentioned that the time she has been active only amounts to a single year. However, whilst she is sleeping she replays what she experienced over and over again, instead of dreaming, so that can still be factored in. Still, Nasu said she has the mind and body of a 19/20 year-old woman, so she can't be measured by common standards.
Kinda like Irisviel, who has the life experience of a 9 year old person while still having the mind and body of an adult.
