Good growth rates for Epicrates, specifically BRBs?

[Charis]

We bought our first BRB as a 2, almost 3 month old in 2012. Then we got two adults at the end of last year and another that was a few months old. These are our first large boas and I just want to make sure that the young ones are growing at good rates. Our 2012 seems like she might be a good bit smaller than others her age but she has been growing steadily since we got her. I'm more interested in what the best rate of growth is for healthy snakes, not how fast they can be gotten up to breeding weight. And I'm aware that snakes grow at differing speeds but can you all share what growth records you have on your BRBs that started out as babies so I can get a better idea? I'll post the 2012's, Zoë's, weight records here in a minute too. Unfortunately my record keeping is a bit hit and miss.

Thanks!
