ACCURACY RANGE  INTERPRETATION
                   EBV should be considered as a preliminary estimate. It could change
      less than 50%
                   substantially as more performance information becomes available.
                   Medium accuracy, usually based on the animal’s own records and
      50-74%       pedigree. Still subject to substantial changes with more information,
                   particularly when the performance of progeny are analysed.
                   Medium - high accuracy and includes some progeny information.
      75-90%
                   Becoming a more reliable indicator of the animal’s value as a parent.
                   High accuracy estimate of the animal’s true breeding value. It is
      more than 90%  unlikely that the EBV will change much with the addition of more
                   progeny data.
