The tools cannot estimate burden into the peers network very well, particularly when longest-exit routing is implement to balance the mileage burden, so each party shares their information with each other and compares data in order to make decisions.
It's not common, but there are a handful of peers that share this information with each other.

Admittedly, it's been a few years since I looked at such tools... So please help me understand: does the tool evaluate distance (and therefore burden) as it extends into the peer's network, or just into the local network? And in either case, is this kind of data normalized and shared between peers? It seems like there could be a mechanism here to evaluate fairness of burdens, but I'm skeptical that these tools are used in such a way. I'd be glad to be incorrect. ;) Cheers, -Benson
