The surveys are not accurate. I came up with 46 North America and 49 World (3 International). So I went through my list and my actual is 45 North America and 51 World.
^ I am very confident that it's accurate for currently operating B&M's. I'd love to hear what you think is incorrect though. Which 3 international do you think are missing?
The only note I can make - I did not include Vortex (CGA) or Mantis, but I did include Patriot (CGA) and Rougarou (cause they aren't different than the originals)
