The observations indicate that another process is running on the pico that eats up so much time that 1 % of the positive edges are read over at higher frequencies. The delays must be less than one pulse length of the 10 kHz signal, i.e. less than 50 ns. The suspicion falls on the USB interface, which must be operated permanently.

The solution to the problem again lies in the use of the second processor core in the RPi Pico. The virtual serial interface is initialised in the first core. The actual frequency measurement is shifted to the second core. There is access to the interface with Serial.print, but the transmission of the data takes place in Core0.
