Fide reduced the minimal rating of players to 1000 elo more than 4 years ago.pedrox wrote: ↑Sun Sep 01, 2019 4:31 amUri,
The article tries to establish a relationship between the Aktiv list of dedicated chess machines and the FIDE list. The fact that the Elo FIDE starts at 1000 points or the Elo USCF at 100 is not something critical for what the article tries to explain. The article is not recent, maybe 4 years old and as you know it is possible that at this time the minimum EIo FIDE has been going down from 1400 to 1200 to 1000 and who knows if in the future there will be Elo FIDE minors.
The article tries to explain that if the official USCF conversion formulas between the Elo FIDE and Elo USCF are used, then the Elo of the dedicated machines of the Aktiv list seems to have a good relationship when dealing with Elo (FIDE) above 2000. And if the official formula for lower Elo is used then the relationship between the Aktiv list and the FIDE list does not seem to fit reality, for that reason a different formula is proposed in the article. But all this has to be seen from the point of view of dedicated chess machines.
You are right that there may be USCF players with Elo of 100 and these appear to be class J (100-199). But even so I believe that it is possible to start in some cases with USCF of 750 or with different ones according to other criteria. It is indicated in the document in section 2.1 point 5. But I am unaware of the USCF system.
You can see from table 4 that there were players with fide rating 1000-1299 already in 2010.

Note that based on my experience the fide rating for low rated players is not something that we can trust and I guess that the difference in playing strength between fide rating of 1100 and fide rating of 1400 is clearly smaller than the difference between fide rating of 2300 and fide rating of 2600.
I doubt if the formula that translate 1050 fide rating to 300 CCRL rating is correct.
Note that the lowest CCRL rating at 40/40 is 1377 and if we talk about 40/4 CCRL rating list the random mover has a rating of 260 CCRL elo because they test buggy engines so I do not know how you can compare CCRL elo of numbers like 0 100 or 200 in the table
I do not believe that 1691 of TSCP is translated to above 2000 fide rating at 40/40 time control.
