Could that be called the poor mans cattle crush ? The attached shows a comparison for the Jan. 2013 spreads in 5- 4-10 & 1-1-2 One could ponder which is a better representation of the real world, and/or better trading ratios.
After further review, an evaluation of the 5-4-10 ratio vs. the 1-1-2, I find that the 1-1-2 doesn't work and will show losses while the 5-4-10 shows profits for the same time frame.
