how about a source.. go there and read it?

Too dark to read your numbers...

Anywho.. so your dismissing 88 on a technicality eh?  "not triggered.."

Anywho.. there's weather.. specifically there's moisture.. soil moisture.. temperature.. genetic's.. dieses.. etc.. a LOT of factor's that go into yields..

For instance if a temperature spike hit's during pollination.. at the wrong time "BAD".. another year in the data set.. it's a few weeks later.. "whew" "pollinated.. just took a few points off test weight.."

Same climatic event.. BOOKOO difference total effect.. Late season freezes for Wheat for example.. ditto..

That's why converting "graphs of an index" into US National Corn Yields.. is "risky" at best..

However, again I caution that it's the period within the AMO/PDO cycle that concerns me.. our odds of a "good outcome" are definitely gonna be reduce to what someone who has farmed over the past 30 years is Used to..
