If you put 'World Football Elo Ratings' into Google the top link should give
you 'eloratings.net' - I couldn't get the link on my browser bar.

France is currently top with a rating of only 2022 - even I could beat them!

I found this page some years ago, and kindly asked to borrow
the formulas for a fantasy football game I play. After adding
the results from each week for nine seasons (up to 270 games
depending on how long each team has been in the league), the
current 48 teams range between 1228 and 2389 in rating, with
the top 15 all beyond 2000.

I don't know how representative it is to have 30% of the
participants beyond 2000 in an ELO based system, but I
believe I can benefit from this artificial rating somehow.

I don't think I knew of Elo's rating system being used for anything other
than chess but it's a general enough system that it doesn't surprise me
that somebody else is using it.

To nitpick, it's `Elo', not `ELO'. The system is named after it's
inventer, Arpad Elo. It's not an acronym.

You can't really compare one set of Elo ratings with another. For a
start, it depends on what the initial rating of a new player is. It may
be that the effect you're seeing is a starting transient -- systems like
this take a while to settle down to the `true rating'.

Point taken, although I could pretend I'm used to write surnames
with capital letters as in "ELO, Arpad".

I used 1200 as the initial value for my fantasy league, but since
there is no RD value, rating changes will not slow down over time.

It's a fallacy to think about an ELO rating as a random variable
estimating someone's "true rating," since a person's strength changes
over time (in technical terms, the quantity is not stable).

I'm not really considering the Elo rating as an RV (at least, not
consciously) but winning or losing a game can change one's rating by 1%
or so and I don't think my ability changes by anything like that much
during a single game.
