There is a lot of bad terminology floating around for this. However there is only one important one, and that is how far the suspension drops from full extension with the rider on the bike. I read once in an article about setting up a Ducati that mentioned setting the sag without the rider, but this is only really to help get things ready for the 'average' rider. I never figured out how to make the bike work very well without a rider

It is called static sag by the Racetech, Maxtons and others who modify/improve bike suspension, so I think it is the right term.
