I suppose that's one way of looking at it, but it smacks of being disingenuous, suggesting that something is more than it is. When dealing with percentages, we expect the "whole" to be the sum of the parts and to equal 100%. I know there are instances when the summation can exceed or be less than 100%, but this is not one of them.
Taking this to its logical conclusion and using your phraseology here, if one started at Chicago and listed every station along the Cardinal route, it would go something like this: "44% of the Cardinal's passengers EITHER start OR end their journey in Chicago; 1.6% of the Cardinal's passengers EITHER start OR end their journey in Dyer", etc., etc., until the final station, " 13% percent of the Cardinal's passengers EITHER start OR end their journey in New York." And then logical summation of all the stations: "All told, 200% of the Cardinal's passengers EITHER start OR end their journey at all Cardinal stops combined." And of course, that can't be because there never can be an amount more than 100%!
The problem is mixing ridership on the one hand and combined boardings and alightings on the other. When you specifically state, "EITHER start OR end" you're talking about boardings and alightings. When you talk about "passengers" you're talking about one trip. So it's an apples-to-oranges comparison. And when you're talking about the worthiness of a stop with regard to percentages of the route as a whole, your numbers better add up to 100% lest the anti-passenger train people out there call you on it.
I don't see anything wrong with Cincinnati generating only 6% of the Cardinal's ridership. But instead of mixing and misleading percentages, what's wrong with simply stating that (in 2015) 12,000+ people got on an off Amtrak trains that run three days per week and in the middle of the night but still generate activity equal to about 40 people per train....and leave it at that? I think that alone would be enough to continue a conversation as to how ridership could grow if the train at a different time or every day.
