Binaural Tones with Surf 2 settings

Hi everyone, I’m interested in creating videos with the Audacity plugin “Binaural Tones with Surf 2”, my question is the following.

To create binaural tracks that work but are different from each other, can I change the settings of Binaural Tones with Surf 2 with randomly chosen values, or do I have to calculate the parameters according to some rule?
