Of course, only those players whose identities on ShogiClub24 are known to me could be included. The first column is Pan-Atlantic, second is ShogiClub24. We now have some kyu players on the list, so if someone will rerun the regression it should be more valid this time. I relaxed the criteria for being on the list a bit, to get more data. 2455 2118 2422 2284 2285 1993 2255 2013 2195 1753 2174 1925 2118 1455 2101 1465 2094 1555 2074 1064 2044 1181 2012 1453 1980 1513 1973 1312 1926 1378 1924 1124 1908 1161 1852 1377 1827 1091 1809 1298 1791 1072 1784 993 1772 933 1769 1149 1660 1507 1620 797 1599 1157 1505 635 1272 789 1138 336 All players listed have at least 80 games on ShogiDojo, which reduces the effect of starting rating to under 5%. All players listed have at least 24 games on Pan-Atlantic (16 for kyu players), where starting rating plays only a tiny role and is in any case based on known rank. Player must be listed on 2002 or 2003 Pan-Atlantic rating list. No names are given in case some players prefer anonymity. There are 30 players on this list, eleven more than last time. Six are kyu players. Hopefully this will give us a much more meaningful conversion formula.
