Fargo explained

Thought I would bump this up.

After digging through a bunch of old threads, I found this. The links are very informative and answered most of my questions, but not all.

Can anyone tell me if old results fall off? Do ratings degrade over time for players who have quit playing? If so, how does that happen exactly? Old results falling off or maybe a steady degrading of the rating based on player inactivity?

I feel like I've read something to do with this previously, but couldn't find anything about it when I searched. I also PM'd Mike Paige but didn't get a response. I didn't want to start a new Fargo thread either--there are plenty as it is.

Thanks for any info. And thanks, OP, for posting these links.

Yes the game results fall off over time, and if I recall correctly I believe they fall off completely after 10 years. And over the course of those 10 years before they fall off they start to count less and less and carry less weight the older they become. The games you have most recently played carry the most weight and mean the most. Games you played 5 years ago still count, but are not weighted as heavily as games from last month. And games from 9 years ago presumably carry relatively little weight, certainly less than say your games from 3 or even 5 years ago.

I don't recall Mike specifically addressing how the rating of a player who has quit would be impacted over the course of those 10 years until everything dropped off. Here is what I expect happens based on my understanding of the system. Just like an active player, their newest games (even if they aren't all that new) are still going to carry more weight than their older games, so if they quit 5 years ago their last games from 5 years ago still carry more weight than their even older games from 9 years ago. It would seem that their rating would change over time as older results drop off after the ten years, the same way it works with active players. I would presume that their rating could also change a little bit after they quit, especially at first, due to the changes in ratings of their past opponents (again the same way it works with active players). When FargoRate finds out that the 417 rated player you beat was actually a 606 rated player who was incorrectly rated for whatever reason (most likely because they had few games in the system and under performed at first) your rating is also going to go up a bit to reflect that it was actually a 606 you beat in that match and not a 417.

Lots of information can be found at the following links, and Mike has gone into even more detail on the above and other aspects of the system in many different threads on here.

The ratings are weighted with a "half-life" of three years. So far as I know, no match result is ever deleted. If a match is 12 years old, it has a relative weight of 1/16th.
 
I would still like to know how to submit weekly tournament results from a local pool hall. Nobody had explained that.

The system is going to fail to grow unless it can be easily adapted and used.

I said the games fall off after ten years but you may be right. I had heard that number thrown around on several occasions, including in threads that Mike participated in (at least I thought so but maybe I am remembering it wrong), so I presumed that this was correct or that Mike would have corrected them. I can't for sure specifically recall hearing it directly from Mike though so people should probably regard the "falls off after ten years" thing as being untrue or at least unknown until and unless Mike confirms it. It could even be that how long results stay in the system and the exact weight they carry at certain points in time are proprietary aspects of the formula that Mike does not wish to divulge.

You should contact Mike directly to see what the vetting process is and what match results he would be interested in obtaining and in what submission format. His user name on here is "mikepage" but it may be better if you email him at mpage@fargorate.com instead.

I think I have heard or Mike has said that he has software coming out in the near future that will help facilitate the easy and seamless transmission of match results for those with the software.
