An EPD is an estimate of breeding value. The higher the accuracy the smaller the standard error associated with that estimate. There is a 68% probability that the actual EPD of the animal is within one standard error of the estimate. 84% probability that it is within two standard errors and a 95% probability that it is within three standard errors.

Now that we have the statistics out of the way...an EPD, no matter what the accuracy, has absolutely ZERO predictive value of actual performance. There will be natural variation of any actual data. What matters is the average, and how that average compares to the other sire groups in the contemporary group. If this was the only sire used in the contemporary group then the data is useless and therefore cannot be used to make recomendations about the bulls breeding value or how he should be used in the future.
