Centre county Pennsylvania, USA | Great questions, Thanks. I'll try to answer some of them.
(1) "would gross revenue show any type of pattern?"
I'm thinking on that one, might take awhile but I'll post it when I'm confident that the answer is both reasonable and supportable by USDA data.
(2) "Do increasing trend yield mean more bushels can be paid as rent?"
Yes. Attached chart shows the increasing trend yield for IOWA geographical area. From that chart, trend yield in crop year 2014 was about 10 bushels/acre greater than trend yield in 2008.
(3) "Do big crops make farmers more apt to pay more the following year and vice versa on small crops?"
Not sure about big crops, but do know that high market prices make it easier for us to give our landlords more rent money. Problem with big yields is that they are not necessarily correlated across all geographical areas. I've got a chart somewhere that illustrates that behavior, but cant find it now. From memory, 2012 was a year of very low corn yields at the national level (almost 3 standard deviations below 2012 national trend yield), but our 2012 corn yields here in PA were above PA's 2012 trend yield.
