Healthy weight range

Is there a healthy weight range "formula" for ball pythons? I'm thinking maybe something based on age/length/gender that would help me determine if my snake is eating enough? I've looked but haven’t found much. One of my snakes is a male who weighs 460 grams. He's probably 1-2 years old but I'm not really sure, I adopted him and didn’t get a ton of info from the previous owner. I've yet to measure his length but probably ~30". He scarfed down a f/t adult mouse last weekend, not sure if I should try feeding something larger or not. He's a fair amount thicker than these mice, which are smaller than I expected ("gourmet rodents" from petco... looking for a better source). So much so, that once he's swallowed it all the way there isn't even a "lump"...

There is no formula while a 1 year animal might weigh a certain amount of grams another might weigh more or less, it depends on a lot of variants, how fast the animal get started, type and number of prey fed each week, feeding frequency, whether the animal is a strong feeder or picky eater etc.

The most important is that your animal is healthy and look healthy.
