It would appear that we are headed down the road of confusing average
and mean. Which are totally different. Given 10,000 freight cars past a given point, the average will most likely mimic the national fleet based on Tim and Dave's data. However, the mean may be skewed in one direction or the other significantly.
====================

Tim's data doesn't say that. He has the percentages of system and foreign ownerships on line and off line. It's a big leap of faith to extrapolate that distribution of individual ownerships.
