Except there are plenty of examples where someone could relatively easily earn 200-400 points a day solely on long distance trains. Basically anywhere that you could do a same-day turn on Amtrak, you could earn 200 points. If there were two train numbers (say, 8 and 28,) you could get 400 points in a day just by doing a split ticket on those trains and going two stops. For example, someone going from MSP - WIN could do MSP - RDW 8, RDW - WIN 28, WIN - RDW 7, and RDW - MSP 27 for under $50 on low bucket with the multi-city tool. That's solely long-distance service, all generally during waking hours, and while there's a long layover in Winona there's a small bus system Monday - Saturday that can get you around to explore the town, go to a restaurant, coffee shop, or whatever. There's certainly tighter connections that could be done elsewhere along the routes. It was certainly "very usable" along at least parts of the long distance routes, so it's fair to say that it wasn't a corridor-specific advantage.
