I can see at least 5 players in the platinum who shouldn't be playing. IE, they play 740 speed. Shows how data can't help and human discretion would.
Well first that doesn't show that data doesn't help. It shows the opposite actually. It shows that not having data (or in some cases just not enough data) is what can be a problem. But we already know that.
In years past they placed people by known ability when it was known. Do we know for a fact that they are not using similar discretion this year too just like in years past? People that would likely be "known" will likely have a Fargo Rating anyway so the situation probably won't come up that often, but when it does, and they know a player is much better than their starter rating would suggest are you saying they are not going to move them into the appropriate division? Do you know this for a fact, or are you just guessing and assuming? I don't recall this ever being specifically addressed but I find it hard to believe they would leave somebody they know to be a grand master in the Gold division just because they don't have games in the Fargo system.
On a side note, if there is not a robust Fargo Rating they sometimes don't have a way of knowing if someone is grossly under rated unless somebody tells them. Whether you should rat them out or not is an issue that people will disagree on (and that I am going to leave alone for now) but what seems pretty obvious is that anybody that knows of people who are grossly under rated and chooses not to bring it to FargoRate's or CSI's attention has zero business ever complaining about there being people who are under rated.
Last year I said I would take one player to win the open, and he won it undefeated. So I think Fargo is a good thing, but I will guarantee players who win this year. Will go up by over 50 points,
One solution is that if anyone goes up by more than X number of points, say 50 points, then they are no longer eligible to win prize money in that event.
Or even better and more fair, since it is easier for players who have no games in FargoRate to move up more (and more quickly) than someone who is very established with a high robustness, you can do it by percentages based on robustness level. If a player with a 200+ robustness level has their Fargo Rating go up by more than 5% (like a 600 moving past 630) they become ineligible for prize money. If someone who has no FargoRating at all and had to be assigned a starter rating goes up by more than 10% (like a 600 moving to 660) they become ineligible for prize money. And in the middle, if someone with a robustness of 100 games has their Fargo Rating go up by more than 7.5% (say a 600 moving to 645) then they become ineligible for prize money. Nobody is going to move up that much by "playing over their head". The only way it is going to happen is if they were grossly under rated at the start. Put it on the players to make sure they are rated in the vicinity of what they should actually be.
Going that route would certainly put a stop to players trying to be too dishonest about what their starting Fargo Rating should actually be. I am not not necessarily advocating for this and it comes with its own set of problems but I guarantee it would cure all sandbagging or people slipping into the wrong divisions because they weren't known. Players would start looking up the Fargo Ratings of the other players they knew to get a rough gauge of where they should be rated and they would be contacting CSI in droves saying "I don't think I should be a 525, it looks to me like I am probably right around a 580, please adjust me accordingly".
I am pretty certain though that Mike Page and Mark Griffin have both already thought of this and probably even discussed it and have decided against it for one reason or another. But it sure would take care of the problem you mention. You (and others) just reporting them would also take care of the problem too. Not reporting them is fine too but in that case I think you give up the right to complain about under rated players.
