Perhaps, but the results are no more valid than the raw data.  And after talking with several farmers over the years I am hesitant to accept Pioneer rep's raw data.  It pains me to say that, and I hope things have changed over the last couple years, but I remember a farmer telling me the published data didn't seem to match his records.

We produced seed corn for Pioneer for several years and I have nothing but praise for the folks on the production side.  But the sales side has irritated me time and again.

On a side note, I am having more and more trouble trying to make plot comparisons.  With the almost unlimited number of trait combinations and the speed with which a variety goes from a "hot new number" to "one of the things they dropped this year" I have difficulty working up valid comparisons.
