World Record - TTNMapper errors?

I first heard about LoraWAN through a FLAT EARTHER (sorry!) posting about the world record 1336 km record from Portugal to the Canary islands.

I understand tropospheric ducting, and am aware that it is particularly strong and frequent along that corridor. That’s all fine and dandy.

What I am curious about now is that I can see beams in the TTNMapper that are much longer than that 1336 km, but for some reason, aren’t considered a new world record. For example, in the “things-virtual-balloon” experiment, there are a handful of packets between the Netherlands and a receiver in Seattle, WA.

Can anyone explain these records in the TTN Mapper? Are they errors?

2 versions are possible:

a) the mapper device sends wrong gps data which can occur in early states with not enough fixes
b) the receiving gateway has wrong coordinates. (e.g. lat/log swapped)
