[@Imperfectionist] Wow, you've put in a lot of work for this. I really appreciate all that you've done so far.
I wouldn't mind following your formula and completing the routes for you, if you don't find a problem with that.

There's just one item I was thinking needed clearer description. The Travel Times (specifically the "a day" descriptions) are a little vague. Does "a day" mean 12 hours, 8 hours, 24 hours?
Perhaps listing it as "4kph or 30km in 8 hours" would be more definite in something as "specific" as this. Still, the math doesn't quite work out. 
If we just do the hard math from the "day's travel" with the speed already determined, we'd have this:
30km in 7.5 hours.
100km in 6.67 hours.
130km in 6.5 hours.
Flight would be undetermined by "days" (though it wouldn't need to be determined by "days" unless you're traveling out of the region).

So if we want to go for 8 hours, it would be the following:
32km in 8 hours.
120km in 8 hours.
160km in 8 hours.
800-1600km in 8 hours.

The math would obviously differ if you wanted to define "a day" as something longer or shorter, however. I just noticed how "inconsistent" it was (though not dramatically).

I don't know what other factors you put into those numbers. So if I'm totally off, then ignore everything. xP

Regardless, if you'd like to take a break from it (and focus on your post), I'd be totally willing to finish it up for you. I love doing stuff like this anyway. xP
But, yeah, this looks amazing. Probably a niche thing to love something like this, but I'm a freak about numbers >.>
