First of all, it's obvious that BPs can greatly vary in growth rate, but what's the average growth rate for different ages in grams?

Basically, what's the average expected growth of a 500 gram snake? How long until it might be 1,000 grams, 1,500 grams, 2,000 grams?

What's the average expected for a 150 gram snake to reach 500? etc...
