Not entirely sure though the ratings here are not elo but glicko.

Another thing to take into consideration is people at USCF tournaments will be stronger strength then the people playing recreational chess online

ELO ratings used in chess (and tennis etc.) are relative to a particular group of practitioners.
Anybody know "roughly" how the ratings here compare to USCF ratings? (U. S. Chess Federation)
For example, if you have a rating here and USCF, is your USCF rating 200 points lower? 100 points lower? etc.
OR if you just have a gut feeling, what do you think?
Thanks ;-)
