[QUOTE="ArmyDoc, post: 740480, member: 6832"] I decided to search on the top bulls based on BW, WW and YW. Their performance data and progeny averages are all over the place. For example [url=http://search.redangus.org/animal/1187338]http://search.redangus.org/animal/1187338[/url] His numbers are: ....CED BW WW YW EPD -3 4.5 64 108 Acc 32 63 54 44 . % 97% 98% 1% 1% Performance Data .....BW WW YW Data 80 780 1303 Ratio 97 111 111 Progeny averages ......BW WW YW Data 89 746 1332 Ratio 109 107 108 Groups 4 9 7 Progeny 27 27 16 OK, so far so good - top 1% so WW and YW are very high, BW and CE as expected are low. But what about this one: [url=http://search.redangus.org/animal/953895]http://search.redangus.org/animal/953895[/url] His numbers are: ...CED BW WW YW EPD 8 1.2 65 111 Acc 36 66 58 49 % 27% 70% 1% 1% Performance Data: BW 60 WW 559 (no YW listed) Progeny Averages .....BW WW YW Data 72 503 890 Ratio 100 105 114 Groups 16 20 4 Progeny 60 59 5 How can this Bull be listed as being in the top 1% for WW and YW, but have progeny Averages that are #250 lower for WW and #400 lower for YW?
