I have questions about elo rating inflation.

1. Does it exist, and if yes
2. Where does it come from?

I had one idea: Since there are more very strong GM's "available" than i.e. were
in the seventies, an even stronger "Super GM" can reach higher performances. -
Just because he doesn't have to play that many opponents which are much lower
rated, like it was unavoidable probably in the 70's (when there just weren't so
many 2650+ players at all).

If this is true, it would mean that you can reach *higher elo performances with
the same strength* today (because you have more stronger opponents available to
beat).

If this is so, then the top ranks of the SSDF list are also affected by that,
most probably (?).

Thanks,
