That seems extreme. I divide it at the 360-mile price jump, but I woudn't be surprised if far doesn't kick in until 500.
I mean, I'm from Chicago originally. 360 miles is Minnesota or Kentucky, 500-550 is Virginia Tech or Kansas. So actually, yeah, I'd say that 360 is neutral and 500 is "far from home" if it proceeds logically, which I'm sure it doesn't.
