Btb, Ive looked at the latest annual report the 07/08 report and compared its embryo count data per wmu (data gathered from 2005-2007)and compared it to the year befores annual report, the 06/ 07(data gathered from 2004-2006) and of the 22 wmus on the chart, 12 of them showed decreased embryo count on the 07/08 report. Over half had experienced at least some rate of decline.

That most likely would equate to lower adult doe bred percentage as well. That would lead one to believe that it was not "shifting" samples, but that many of wmus had declined despite further reduction.
