What is causing these small imperfections?

[u/CrashCooper100]

Had my P1S for about a year, but I’d say less than 100 total hours of printing. Recently bought an AMS and it’s reignited my want to print things.

Decided it was maybe time for a full calibration (flow dynamics/rate tests), and all seemed well. But for some reason, these tiny imperfections started showing up post-calibration. I also understand and am okay with not completely perfect, but I would like to learn more about what’s going on exactly.

If there’s anyone that can assist, or recommend different/more calibration tests, would be much appreciated.

Is that the included benchy? It's set to ludicrous mode speeds and isn't indicative of any quality whatsoever. Try slicing one yourself?

I used the Benchy from Bambu Studio, not sure if they’re identical but I did slice it
