I disagree. While it may be hard to make an exact comparison, I would venture that the 'quartile correlation' (i.e. the correlation between players in a given quartile ICC blitz, and the corresponding quartile USCF) would be pretty high...perhaps in the .9 or higher range. The decile correlation would be lower, but probably still significant. I'd like to see some hard numbers on both of these, though. While you may not be able to say that an ICC 2200 blitz is a USCF 2100, I think you should be able to say a 2200 ICC blitz is quite likely in the top quartile (1900 maybe to 2600) USCF. It's certainly not exact, but the correlation between different types of chess exists. I don't run across too many 2200 USCF players who are 1300 blitz, or 1500 lightening.
