text: For offenders who receive the new EDS sentence an adjustment is made to 
  the percent of custodial length served to reflect that these offenders will spend 
  a greater proportion of their sentence in custody than standard determinate 
  sentenced offenders discharged to date. 
  
  Projected prison receptions are sub-divided by age category (Juvenile, Young 
  Adult, Adult) with the exact age of the offender attributed in the same manner 
  as the custodial sentence lengths. This allows the model to explicitly age the 
  offenders whilst in prison (e.g. move from Juvenile to Young Adult categories).
