I haven't seen the video myself, but I'm interested in knowing more. Can you point to the timestamp where it makes these claims and how the analysis was conducted? Maybe there's something I'm missing.
You'd have to watch the full video in order for us to discuss it properly, you seem to be missing key details. However it is only available paid on demand (2000 mules dot com), not on a free streaming service.
The location analysis is explained throughout the film, but it's mainly after the intro and before going into the state security camera footage / general discussions.
The main point I was making it the location path and frequency of dropbox points is how they filtered people out. They only took people that went from one dropbox location to another dropbox location, at least 10 times. Then they analyzed how many times those devices went on those routes and how many devices met that criteria in total.
