Ouch, don't put my name in all capitals, I don't want draw attention to any mistakes I might make!  Truth be told, I'd been thinking Iowa potential was maybe at the 185-188 area, and maybe that's still within the margin of error from FPT.  Obviously they were 5 bpa high last year vs. NASS, no reason to think they couldn't be 5 bpa under this one.  Even 188 wouldn't be a huge uptick in the trend/flatline of the last dozen crops or so, though.  I'm not sure what to point at for reasons.  It's not lack of cutting edge machinery, triple stacks, or other technology.  I'm skeptical of genetic top end improvement in these hybrids, though.  Traits can only do so much.  Probably more to the point, it's just tough to get consistent weather across the whole Iowa crop.  If Missouri is burning up, probably that bleeds into Iowa.  If a 40 mile wide hailstorm whacks Nebraska, probably it ends up in Iowa.  If planting delays or a frost are hurting Minnesota, probably that impacts some of Iowa.  

PS.  Unprofitable commodity prices causing some yield loss because of less input dollars spent?  Yes, I'll totally buy that.
