I’m transmitting a max of ~16500 chars (but most times way less) 25 times a second from a Python script to a Teensy 4.1 over USB. What baud rate would be more appropriate? I found this article listing error rates at different speeds for different models, but Teensy 4.1 is missing. Thank you
Recommended baud rate on Teensy 4.1

Two parts:
a) The table you mentioned should be updated to include the Teensy 4.x boards.
I added an issue to Paul's website needs work project: https://github.com/PaulStoffregen/Website_Updates/issues/26
b) If I am understanding correctly your Python code talking to the Teensy over USB? i.e. Serial object. If so the baud rate specified in Serial.begin() does not matter. The
Teensy transmits at USB Speed. The baud rate is ignored. And USB Serial on t4.x is very fast (T3.x connects a USB full speed 12MBS, where the T4.x connects at USB high speed 480mbs)

Indeed the baud rate is ignored by USB serial, so it doesn't matter what baud rate number you use. Detailed documentation is here:
