Re: Championship Event - Where the "Random" Match Sorting Really "Shines"

So rather than
Code:
1 4 7
2 5 8
3 6 9
You might have lists like
Code:
1 6 5
3 9 4
7 2 8
On average, they will even out to have the same number of powerhouse teams.

The whole tiering thing seems to be a wierd solution to a problem that didn't really exist anyway. Now instead of a few teams sometimes legitametely complaining that they got a bad deal in the pairings, you've got a whole group (the veteran teams) who get a bad deal, and they can prove it.
I suggest a modification to your idea which sorts the teams the same way as the divisions at the championships.
Current method
V M R
1 504 1207
2 505 1208
3 506 1209
A V team can never play another V team in the random pairings
Division Method
A B C
1 2 3
4 5 6 Low Pool
7 8 9
501 502 503
504 505 506 Mid Pool
507 508 509
1201 1202 1203
1204 1205 1206 High Pool
1207 1208 1209
This distributes the allegedly strong lower number teams (< 400) into three groups. Now a veteran team will still be paired with a midrank and a rookie in its division but it has the possibility of playing against 67% of the veteran teams
