Maximum efficiency/cadence for the most part - big gaps in gear inches staggered between the biggest and smallest cog unless it's a racing cassette/freewheel. In addition to my 9 and 10 spd cassettes, I have a few bikes with 5,6,7 freewheels; no big deal. Just ride, don't worry about such nonsense.
