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.
