What determines how many Poké Miles you earn from Streetpasses, and is it possible to increase it?
I ask because I always only earn a single Poké Mile per hit, which seems hilariously low considering any kind of online interaction yields far, far higher numbers - I think a single Wonder Trade yields about 40. It's not even worth bothering checking the Streetpass data for: I have ~13,000 Poké Miles in total, of which only about 10 were gained through Streetpass. Granted, I Wonder Trade a lot, but that's still a ridiculous ratio.
