Irian Jaya weight

[kazz]

Hello.
My female Irian Jaya has weight 580g and length ~1.25m and she is ~1.1 year old.
I've found next information here Morelia - Irian Jaya carpet python page - Morelia spilota varigata Irian Jaya carpet pythons information

Irian Jaya carpet pythons reach sexual maturity at 18 months to 3 years of age, at length of about 3 feet for males and 4.5 feet (1,3716m) for females.

So I am guessing whether she has too heavy weight and she is too long for her age ?
Well I have a thread with identifying my snake and may be I have irian jaya +cheney ?
What do you think guys ?
Thanks.
