I was looking for hese famous "rules" and was amazed to find that i was not allowed to have a player be twice in the 5th seat but nothing prevented a player to be twice in the 1st seat.

Rule 7 prevents it:

7. A player doesn't play in the same seat position, if possible.

Interesting link anyway (I understand at least what "NOAL" means, thought it was something like "no alignment" :D)

Anyway, since the goal is to distribute equitably transfers, you can't be first then second for instance.

Being 5th is worse than being 4th. But I don't know if it's worse than being first. I remember lost game because I was always one turn late vs my predator.

Ok, it is debatable if 5th is better or worse than 1st.

But actually, it IS debatable... Which also means that there is a criteria which prevent one of those starting place to be duplicated while the other can be (and is).

Why should it stay like that ?

Is it possible to review these "rules" ? (and maybe update them).

No. If possible, seating positions can't be duplicated. Or I don't understand what you're saying.

Moot because your premise is wrong.

The rules I found in the link above are these ones :

1. No pair of players repeat their predator-prey relationship. This is mandatory, by the VEKN rules.
2. No pair of players share a table through all three rounds, when possible.

3. Available VPs are equitably distributed.
4. No pair of players share a table more often than necessary.
5. A player doesn't sit in the fifth seat more than once.
6. No pair of players repeat the same relative position[*], when possible.
7. A player doesn't play in the same seat position, if possible.

8. Starting transfers are equitably distributed. [NOAL]
9. No pair of players repeat the same relative position group[^], when possible.


And we have rule 5 who is considered more important than rule 7 which have an "if possible" in it.

I was speacking about that.

The rules I found in the link above are these ones :

5. A player doesn't sit in the fifth seat more than once.
7. A player doesn't play in the same seat position, if possible.

Currently (for seatings up to 23), rule 7 has never been violated: it was always possible to seat the player in another position.
This is also enforced by the fact that in order to have the best distribution of transfers, a player can't seat twice at the same position.

So, there's no need right now to change rule 7 or 5: rule 7 is a superset of rule 5 and the "if possible" clause has never been broken.

You are in your hunt for the best seating for 2R+F tournament.

But I was speaking of the seatings for 3R+F tournament where for 5 players tournaments, we have player 2 who play 2nd then 1st and 1st.

Without looking for extreme cases like 5 players tournaments, in 10 players tournaments, players 2 and 7 play twice in the second place and 3 and 8 twice in the 4th place.

EDIT : and in 15-players tournament, 3 and 8 play twice in the 3rd position

(I will not check furher because i is obviously less likely to happen and I do that "manually" checking the tables in the archon (1.5c which I downloaded yesterday here in vekn.net)
