Is my snake growing too fast/am I overfeeding?

Hey all! I documented the trials and tribulations of Koh, my first BP in my progression thread.

But I think she may be putting on weight too fast. I'm trying to follow feeding guidelines but it seems like she is moving up the scale so quickly.
I got her when she was 68g on January 2nd 2020. She was a hatchling (no exact age known) on small mice.

I switched her to rats straight away and since then she has moved up from fuzzies, to small weaners, and has just come off the large weaners. At month 4 she was 390g. I feed her every 7 days, and she has skipped some due to shed.
It's now almost month 6 and I gave her a small adult rat. It just seems way too huge for her, but she's 510g now, and it was maybe a little bit bigger than her middle. Does this progression/feeding regimen sound about right for a 6 month old female ball python, or should I slow down a bit? Feeding charts suggest I should stick to small rats... large weaners seem too small, and small rats too big. Any guidance or suggestions?

Here's the last feed and you can see how it's such a mouthful. The last thing I want to do is overfeed her.

If they prey is bigger around than the snakes widest girth, its a bit too big. I would stick to the smaller rat.

Remember that snakes do NOT need a perfectly exact feeding schedule either. So if you can't find the "perfect size" prey, leave more time between meals if the prey is
on the large side, & don't stress over it if it's on the smaller side, as our snakes mostly eat way more in captivity than wild ones do, AND with less exercise. ;) Snakes in
the wild don't live by feeding schedules.
