This is only true if those players never leave the area to play anyone else. Fargo is a national ranking vs who you play and who the players you play have played. So if you have 10 players living in a bubble in their area and never play anyone else, you will need to first get a ranking for one of them, which is then used to base the others. A "seed" ranking of sorts, it has to start somewhere. So if player 1 can run out every rack and we have a known skill for that, say 750 which is pro level, you assign him that. Then the other 9 play him over a few 100 games, and based on how they do they get a rating.
Statistics work, with the correct data and enough of it, which Fargo does pretty well, better than any other rating system. APA is a closed sphere with players faking handicapps often, same for most leagues. Local tournaments often don't understand ratings properly to assign them. Fargo does it simply by EVERYONE playing EVERYONE and comparing them. So if you play me, you are not just raking you vs me, you are ranking you vs everyone I played in Fargo over all my events. If I am a 550, that means compared to the 60 players I played, that is where I fall. If you beat me and are a new Fargo player, you will be a 550 or higher depending on how badly you win. You beat me 7-2, you are likely to be put in as a 600 or higher. I beat you 7-6 you may be in as a 500 or 530. And this is done over a hundred matches, with a web going across the country. APA does not do that, they really only can match how you play against others in your area. And that is all relative, so is not a good system, never mind the fact that half or more of the players are not doing their best to keep handicaps low, that also does not help one bit. Fargo is harder to cheat unless you plan on losing in every event you play in since it's reported to by non-handicapped tournaments.
Fargo and the real ABCD ratings are not based on the area you are in, but how you play in general. Fargo does compare players against each other, but there is so much data in the system from open events, pro events, non-handicapped events and even handicapped events that the comparison is valid world-wide. APA and other leagues are all handicapped based in the first place and don't link players across areas, Fargo does.
If every league and tournament used a single rating system, we can actually have a valid rating system with less cheating. Fargo is the closest thing we have to this. I can play in my USAPL league and get a Fargo rating, when I play in my local even race tournaments they report to Fargo so my rating is based on that, when I play in the Joss tour they report to Fargo so I get a rating based on that. 40-50 matches and my rating is pretty solid and fair based on all the people I play. Only an idiot or a scumbag would dump every event they are in to win some Vegas trip, but APA does not look at anything other than APA so it's easy as hell to cheat there. If an APA 5 plays in some open event and beats a bunch of A players that are 7s, APA rating does not see that. Fargo would.
There have been a dozen or more posts about the Fargo ratings and local vs general ratings, like when someone said a 700 female is not as good as a 700 male, it's just not understanding the data the system uses and how it works. Female, Male, local, world-wide, it's all the same to the Fargo rating, with the exception of a closed bubble where the players inside never play anyone else and they start with a bad rating to begin with. As the old computer saying goes, garbage in, garbage out. If you take those 10 players that never play anyone else, and you base the top player as a 500 when they should be a 700, then you have your false rating that is localized. Then when one of those players go play someone else, they are all of a sudden 200 points off what the rest of the world is, and that will simply be adjusted the first time they play anyone else and people notice the difference in skill.
