Online chess rating will typically be a few hundered points higher than OTB rating, however it ultimately depends on the person.
Rating diffrence

It is alot, my USCF rating is 1206, but my rating here is 1626. Although I know I am underrated by USCF, opponents at 1200 I have easily beaten.

well... at the medium levels the rating difference is somewhere between 100-200+ points in most cases. so an 1800 rated player is at most cases an 1600 in OTB, and a 2200 might be a 2000 in OTB. but when you reach the highest levels of chess.com the rating inflation factor might give players with a 2200 OTB the opportunity to reach 2700 if they are consistant and play a lot of games over a lot of time on chess.com.
i remember that about a year ago, when i just signed in. the games with the highest rating from both opponents were about 2400-2500. now it's the same players with 2600-2700 ratings. inflation!!!!!!!
What is the average diffrence between your OTB play and your online play in refrence to rating?
