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. 2422 2284 2285 1993 2255 2013 2195 1753 2174 1925 2118 1455 2101 1465 2094 1555 2074 1064 2044 1181 2012 1453 1980 1513 1926 1378 1924 1124 1908 1161 1852 1377 1809 1298 1784 993 1769 1149 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 30 games on Pan-Atlantic, 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 19 players on this list. The average spread is 557.5 points, more than I expected. We need to do a linear regression on the above numbers. If anyone can perform this for us easily, we would appreciate it, so I don't have to rack my brain trying to remember how to do it on my calculator or how to work downloadable software.
