...Wouldn't that make Heather better?

I mean if u think about it. If Astrid was training ever since she was born (which she was, I agree on that...to an extent, I mean I doubt she carried an axe since she left the womb, so technically not since she was born but oh well...) yet Heather has reached her level in a shorter time-span, so in that logic Heather is better since she improves more quickly.
