Weight by age

Im just curious if anyone knows what the average weight should be according to the weight of the ball python. For instance 6 months old, a year, 2 years

Weight and age don't correlate well with balls. Feeding rate, sex etc make too much difference on weights. Sure would be nice though :)

I have about 40 BPs that are 8-10 months old and are being fed every 7 days, all ranging from 250-800 grams. Most are in the 400-500g range. It really varies per snake.
