15 month old female hognose

Hey, just got my first long buddy roughly three weeks ago. Shes 18 inches long & weighs 56 grams at 15 months. Just curious if this is a pretty average growth rate for females or is she growing really fast? She eats like an absolute champ every 4-5 days and shes already longer than some males get so I'm curious! I have a feeling shes gonna be pretty big someday.
