I'd need some Crosstables results of as big as possible round robin
tournaments. Where can I find them ? Computer tournaments could be good too,
but human would be better.

If memory serves, the biggest round-robin, in terms of number of
players, was New York 1889, won jointly by Chigorin and Weiss. There
were 20 participants, and they all played each other at least twice --
in some cases three times, because in the second cycle if they drew
their first game against a given opponent, it was replayed; only a
second draw counted.
This crosstable can be found in any number of books. The best
reference for crosstables in general is Gaige's "Chess Tournament
Crosstables"; it has 4 volumes covering 1851-1900, 1901-1910,
1911-1920, and 1921-1930 respectively. However, they are a bit hard to
come by. Two books currently in print that have NY 1889 are "Amos Burn"
by Richard Forster and "Chess Results 1747-1900" by Gino DiFelice.
Another you may be able to get most cheaply is "The Complete Book of
Chess Tournament Crosstables 1851-1948" by Rick Melton, though it is
seriously misnamed, being nowhere near complete with too many errors.
The DiFelice book is OK for tournaments, but not so accurate about
matches.
