Reality Dysfunction Indicator

The Reality Dysfunction Indicator is a specialized sensor used by Despatch to gauge the severity of a Trans-Dimensional Snatching incident.

The RDI measures:
 * The Reality Slip of the local area, as a percentage
 * Reality Disruption stage (a typical trans-dimensional snatching of the Fellowship was gauged as a Stage Two)
 * Number, gender, and average and median age of kidnapped characters
