+3800 RPM == 64 rounds / second.

+To measure speed one need at least 3 angle measurements per rotation.
+This results in at least 192 measurements per second which is about 1 per 5 milliseconds.
+
+Given that the ESP32 can block for a second, it can not be guaranteed to be up to date.
+Not for speed, but also not for total number of rotations.
