Joel: I don't mean to question your math, but I have been doing some of my own math and just don't seem to agree with you. In KY, for example, you indicate that the 170 bpa is "a stunning 102 bushels higher or 250% greater than last year." Well, in my mind that means that last year's yield was a paltry 58 bpa. So if you move to "250% greater," that means yields in KY would have to be 203 bpa this year. I am not trying to be a pain, but I do think you should check you math. Once you say "250% greater," that means 3.5 times the base year of 58. For example, if someone says they "increased their yield by 100%," that means their yield doubled from say, 100 bpa to 200 bpa. I don't mean to be fanatical, but I do believe your math, or perhaps your nomenclature, is incorrect.

Tom, if my math is correct your figures aren''t right. 170-102 should be 68, not 58 thus adjusting your subsequent figures. Didn't take time to do the math on them but I think the bigger point here is how our reports ( especially government ) throw figures around like this and then later come up for some "reason" to readjust for the sake of moving the market. Figures are figures and math is exact yet one thing I've learned from farming is that figures in farming aren't always what they seem!!
