One reason that they MAY overestimate the yield is that the tour is weighted more for the higher yielding central and eastern part of the state vs the Western part where the Acres are... when Western Kansas gets Snow and moisture in time it can really bushel out.. It doesn't appear that will be the case this year...  ???

I believe these are the routes they use..
