How would you categorize your bp's by weight?

For example (I'm just making a rough guess here):
Hatchling 0-200g
Sub-adult 200-1000g
Adult 1000g+


Does this vary between males and females? I ask this since males can start breeding at half the weight of a female, and are generally smaller as adults.

And as a side question, what weight do you usually start breeding your females at?
