range of players at rating tournaments

From the FAQ :

The rating tournament is a short tournament, with only 4 players. You play each player in one game (which means that 3 games will start at the beginning in the tournament, one or two where you have to play first). The players will come from the same range of rating, so a rating tournament should be very close.

So, the question arises: How close is close ?

As far as I can see there is a 'window' on 200 rating points for each level. That is players in the range 1401-1600 is in one level 1601-1800 in the next and so on. Well in fact I dont know exactly. May be it is in the range 1400-1599???:) In Go kyu levels 3-6 is in one group. kyu 7-10 is next and so on.

It seems to be 1400-1599 rather than 1401-1600.
Level n is 200n to 200n+199.
Go is the same if you consider 1 kyu to be the range 2450-2499, 1 dan to be 2500-2549, etc.
This ought to be in the FAQ.
--------
I'm not sure what the FAQ means by saying that rating tournaments should be close; a 3-2-1-0 result (or 6-4-2-0 as Little Golem prefers to show it) is inevitably a common outcome, at least for games where draws are infrequent.
--------
The system is not really very fair.
For example, 3 kyu players are likely to win many of their rating tournaments, but 2 kyu players don't have much chance, and 3 dan players can't get to play in a rating tournament at all at the moment.

There's some that ended with three winners! I know that from experience (or was that in a MC)! It might mean that the games should be close, not the end result of the torney. Right?
