1)Glicko vs Elo systems will make a difference
2) it easy to use an analysis board playing on the web but, we can't OTB
3) trying to compare on line ratings here to USCF OTB ratings is an apples to oranges comparison of playing strength
4) too many people practice different forms of ratings manipulation
5) you don't get mass time outs or tourney withdrawl , during OTB play, in the middle of games, either causing you to lose or gain points in excess
I think these 5 factors make the most difference as to why the comparison can't be made generally speaking. For some people, in certain situations, it could be worthwhile to compare, but proves nothing as it should apply to everyone
This is 34 pages of a complete waste of time. Factors Adam seems to not consider as necessary to contrast between these ratings;
1) Most people have higher standard ratings than blitz
2) Some people play better over the board than via computer
3) Most importantly; this is chess.com NOT USCF.
End of story. Move on.
None of those factors are "necessary" at all. You obviously haven't developed your mind out of the hunter/gatherer state.
Yes these "points" are meaningless.
