NE IOWA/ SE SD | I think your first comment is completely inappropriate and do not appreciate that. We do our best to find an accurate estimate and share the results with everyone.
I explained my differences with the way Chip found his final numbers in the week following the tour as I found out the exact reasoning for chip's departure from the scout data. I will post the link to the post when I have time.
Edit: This is from a post shortly after the Profarmer Tour
"Where I can debate the ProFarmer number (I am not questioning their number, but simply debating) is they compared analog years 2004 & 2005 for Iowa. In those two years Iowa's Profarmer numbers came in 9 bu. under USDA state final yield. I hate to harp on this too much, but test weights can make or break a yield. In 2005, my farm had a very high test weight (58-60) vs. this year where I expect 54-56. So, that increase in yield can roughly add 6% to final yield....or 9-10 bu. "
That was one of the reasons given for the final Profarmer being so different from the scout data. I would like to add that the heat (high temps even at night) and precip in a large part of the cornbelt greatly differed from those two years as well.
