Pete: I know stockmen would estimate "shrinkage" when shipping cattle, hogs or sheep to market. That was a fairly easy calculation based on distance and weather, the shrinkage basicaly coming from dehydration and lack of feed in transit. Grain shrinkage, I imagine, would be more complex involving the age and condition of the car, the quality of the installation of the grain door, the quality of the roadbed, the speed over the roadbed, switching including number of times and how violent the connections and I'm sure there are other factors that I haven't thought of. I was just curious if there was a rule of thumb that railroaders or grain shippers used to say it was a more or less accecptable level of shrinkage.
