Healthy weight?

Hi, I'm the new kid around here. :P
After waiting two days after feeding, I weighed my BP and soaked her to get rid of the stuck shed that was on her for a week since purchase.
She is roughly one and a half feet to two feet, and weighs 150 grams. Is this a normal healthy weight?
Is there a chart I can refer to in order to check healthy weight and size ratios?
Sorry if this has been answered a million times before.
Thanks :)

Sounds about right.

How/what do you feed, and whats your husbandry like?

I feed f/t fuzzies and details on husbandry can be read in my previous thread: http://ball-pythons.net/forums/showthread.php?t=125487 :)

Some of my snakes seem...more naturally chubby than the others. I tend to not go by numbers but what the snake looks and (more importantly) feels like. If you can feel the spine but it isn't protruding, and if the snake is attractively plump but not sausage shaped or shaped like a skinny Colubrid, I wouldn't worry too much. :)
