Pixel 9 Pro XL, high-res photo rate limitations. Is this normal?

I'm on android 15, camera version 9.7 on my p9pxl. I noticed that if I take a few photos in 50 mp mode back to back, the camera button "greys out" and I can't take any more for a few seconds, I assume because the phone can't handle taking any more photos into its "processing queue" or w/e.

Just for fun I checked how many photos I could take in 30 seconds if I just spam the button in this mode - I was only able to take 7 photos.

For other p9p users, just wondering if you experience the same or if there might be something up with my phone or the software. I've restarted/cleared cache on the camera and it was the same.
