I mean, it has been well known for a while that ADCs on ESP32s and rp2040s are not great. If you need high precision and accuracy ADCs, you are not using these chips' ADCs anyway... or if you are, you likely shouldn't be and should be moving to a custom solution.

Yeah, the particulars aren't new. But the well written graphs and data is definitely appreciated.
