V5 motor speed updates a second (for pid)

I was wondering how many times a second the V5 motors update a second for changing speeds? For instance if I had a pid loop running, or just a loop that updates the motor’s speed each cycle, and I wanted to evenly time the loop cycles with the motor speed update cycles (how many times a second the motor update its speed). For 393 I believe it was 50 times a second, or once every 20ms.
