Just an artificial measurement of articulation. It's hard to compare one vehicle to another since not everyone has access to the same trails. And sometimes trails change... so when someone was looking for a standard way to measure a vehicles trail worthyness, this is what they came up with.
Obviously a score of 900 might work better on a rocky trail than a rig that scores only 400, but the lower RTI truck might climb a ledge better due to a longer wheelbase (which can lower your RTI score). So the score by no means tells the whole story.
