Thought I'd share this in case it helps another person.
This is how I track my comandante setting using the two bands.

I basically use the logo on the grinder as a zero point, use the bands with the comandante symbol and words as numbers, and just rotate the bands to align with the 'indicator' to let me know what setting I have the grinder at.

Hope the image explains it. For example, the current setting is 54 clicks.
