Average Growth Rate?

[Laceflower]

I have a 5 month old Northern BTS, and I was wondering if her (not sure on gender, just going on gut feeling) growth rate seemed normal. She was born on June 17th of this year and is currently about 17-17.5" which is amazing considering she was just topping out at 14" when she arrived in September. She eats every other day, and her regular diet consists of:
Protein: about 1.5 tsp per feeding
Cooked ground turkey with runny cooked egg (I make it in batches that I freeze ahead of time and thaw out before use)
Greens: about 1 tsp per feeding
Collard greens, mustard greens, kale (whatever I have of those three)
Veggies: .5 - 1 tsp per feeding
Broccoli, squash, tomato, yellow bell pepper, carrots, green beans
Fruit:
a tiny sliver of banana smushed in so she eats her veggies without complaint
Supplements:
Alternating Calcium and Herptivite every-other feeding

She's always eaten exceptionally well, and I've even begun increasing her portion sizes as she seems more and more ravenous lately. I don't know her exact weight, but physically, she looks great - streamlined, but plump - and has an excess of energy; she's always alert and perky, so I'm not at all concerned with her health. I just want to know if her growth sounds normal to the seasoned keepers out there!
