Growth question and 1st official weigh in!!

My scale came in today so I was able to weigh in my snakes for the first time!
08' Female Het Pied 390g
08' Male Het Pied 448g
09' Lemon Pastel 215g

Now I will be able to observe their grow in size and numerically!

As far as the growth question... assuming the 08's are eating 40-50g small rats every 7 days. What is the likelyhood that the female will reach 1500 by next october, or is there a good chance I'll be waiting longer before he time comes? Just curious =) Thx!

In my opion, I would feed her a little larger rat, about 60-70 grams. It should be the same or little larger than her width but I don't know if she will get to breeding size by then but this would help!
