That sounds plausible. So maybe we get this: outer dial is distance, inner dial is rate, use the duration as a time and choose the letters they intersect?

Yeah, trying this now: align distance(outer)/speed(inner) and speed ('rate' marker from inner to speed value on outer). With this, instead of using the dials as a calculation, you have three points to align them and can isolate a character from the inner dial (radius between marked center and aligned speed/distance values)

• the radius gets close but doesn't really go through 1, so maybe a blank instead
  
• the radius gets over J but also very close to M.
