Swiss Pools - an Idea

Hey so I was eating a sandwich and all of a sudden I had this idea.

As of right now we have two choices for creating a bracket -- round robin, or straight to double elimination (maybe with seeding by teams results or power ranking or what have you). There are pros and cons to each.

Round robin is fair, seeds well, gives players lots of sets. But it takes FOREVER, 3 way ties get messy, and some sets become meaningless wastes of time when a seed or elimination is guaranteed (leading to unsatisfying tournament experiences or sandbagging).

Going straight to bracket is REALLY FAST, and that's about it. Players can get screwed on poor seeds, pressure is high, and paying money to go two and out sucks.

I suggest experimenting with a Swiss Pools system, as a middle ground between lengthy round robin and hasty straight-to-bracket seeding.

Let's say for convenience there are 64 players. They would be split up into 8 pools of 8 at random. In each pool, the 8 players are randomly assigned amongst each other for the first set. There will be 4 winners and 4 losers. For set two, 2 pairs of 1-0's would play each other and two pairs of 0-1's would play each other. This would leave two 2-0's, four 1-1's, and two 0-2's. Finally, the 2-0's, 0-2's, 1-1's who won their first game, and 1-1's who lost their first game, would all play each other.

This would leave a 3-0, three 2-1's, three 1-2's, and an 0-3. Giving weight to winning early, this would result in the following seeding:

WWW (3-0) 1st Seed
WWL (2-1) 2nd Seed
WLW (2-1) 3rd Seed
LWW (2-1) 4th Seed
WLL (1-2) 5th Seed
LWL (1-2) 6th Seed
LLW (1-2) 7th Seed
LLL (0-3) 8th Seed

Then all 64 players would be seeded into a 64 man double elimination bracket.

I think this would be better for multiple reasons.

- It's MUCH FASTER. Only 3 sets are played, none of which must wait on each other, as opposed to RR where everyone plays 7 sets. That waiting part is a big deal, as in RR everyone knows there always ends up being a pool where one or two players hold up the entire pool.

- Sets mean more. With only 3 sets, player interest stays high and there is no motivation to sandbag (unless you're a runaway 1st seed). There's also no useless sets like if a 6-0 plays an 0-6 at the end of a RR pool.

- No ties. 3 way ties are the bane of RR, hold up the bracket even longer, and happen way too often to discredit. Weighting by when you lose also puts emphasis on winning sets and only sets, as opposed to breaking ties by games won. (this is personal for me as I was knocked out of pools once by a jigglypuff that I beat, but took everyone that beat me to Brinstar and 1-2'ed them to edge out a 3-way tie for 4th seed)

- No eliminations. The time saved over RR pools would allow well more than enough time for the extra 2 rounds in a 64 man bracket vs a 32, and this gives more players the real "bracket experience". RR ostensibly gives more "money's worth" but nobody likes being eliminated from pools.

I'd like to hear some feedback on such a system. The only real con I can think of is uneven numbers. 6-7 man pools aren't ideal but play out logically with byes, and 5 man pools get gross with multiple random byes. It might actually be better to do 9-15 man pools and regrettably eliminate players after 4 losses but maybe those with more experience with swiss can discuss and help refine this into a viable alternative to round robin pools.

I'm one of the people who wouldn't make it out of pools, so i'd feel like i'm getting gypped because i'd get 3 matches instead of 7.
howbout a 4-5 round swiss instead?
that takes more knowledge on how to run a swiss, but everyone gets more games.

EDIT:
regarding odd numbers, I would insist on having at least six people in each pool if i want to run swiss pools.

well, you'd still get 3 sets in the swiss poll as well as 2 or more in the actual bracket...

ideally, youd have pools of 8 people and the swiss tourney would work well, but you're not always getting that exact number of people.

and i cant help but think that this has been brought up before...

Sounds like a good compromise between time and matches. I think most of your objections to round robin pools are meaningless, because those are still superior because everyone plays more. However, time is a very important factor in tournaments, and this definitely helps.

So if there's time, round robin pools are still better, but seeing as time is often an issue this would probably be optimal.

yes, you'd get 2 more sets in the bracket. You'd get 2 sets less than RR but a lot of players can attest to playing useless RR sets, and I think that would be a fair compromise for the sake of time saved.

I've seen some people bring up swiss before but I've only seen it in the context of running the entire tournament that way, I've never heard of seeding pools with swiss. If someone can find a thread on it I'd love to read it :smash:

edit: wtf happened to :hunger: ? that was like my favorite emoticon :c

Because WWL only lost to the guy who got 3-0. Doesn't make a huge difference anyways since you're still playing a 1-2. WWL just happens to play the guy who only beat the 0-3 in his pool.

how do we rate between brackets?
is one 1st seed as good as the next?

EDIT: what if each local scene rated their bracket and tournament matches (using some simple rating system). that way, if the winner of pool 1 has a rating of 1543, he'd have a higher seed than someone rated 1222. you see? that would also solve the problem of ties if brackets aren't exactly 8, because average opposition and average opposition defeated are good tiebreakers.

My roommate and I have been discussing this recently. Personally, I think Swiss would be a more efficient, possibly better way to run pools. For the middle seeds where it's not so obvious who's better than whom, you just use strength of victories by taking into account how many wins the person's opponents had.

I'm not sure if this is already common practice or not, but this would run much more efficiently if each pool had a "captain" who knew how to run a swiss tournament...

this just really doesn't make sense...

if persons a b and c are all 2-1, they're 2-1, nuff said

I don't wanna be ranked below person c just because they only lost they're last match where as I lost my first match, that's just dumb, it's pools

People should try running a smash tourney like they do yugioh/pokemon/mtg and run swiss elimination. ;D

Takes about the same amount of time as pools does lol.

no I do, I just think it's dumb

it's like having a bunch on mini brackets before the main bracket, which is just weird
but if you're 2-1 and lost your last game, your loss was to someone who went 3-0

while if you're 2-1 and your first game was your loss, potentially you lost to someone who only went 1-2...though you also may have lost to someone who ended up going 2-1 or even the 3-0 guy

but its all immaterial, in the bracket (if everybody gets in) you're still playing someone who went 1-2, he just had his victory in his first game (ie the worst loss he can have is to someone who went 2-1) instead of his last (ie only beat the guy who went 0-3)

its based on a probable difference (and in seeding, what isnt), not necessarily something true

Can someone make a picture... or make a hypothetical with persons 1-9 to explain how this works. I've read all the posts and have seen it mentioned before. I've looked at the wiki page even....

I still don't get it :cry:

i like it spikes

how about this food for thought

this saves so much time

2 rounds of swiss pools?

or even 1 of swiss to a round robin

endless possibilities

there are 8 players
A,B,C,D,E,F,G,H

Round one
A (0-0) v B (0-0):::A wins
C (0-0) v D (0-0)::: D wins
E (0-0) v F (0-0)::: E wins
G (0-0) v H (0-0)::: H wins
Players are then separated into groups based on score, and paired within their groups

Round 2
A (1-0) v D (1-0)::: D wins
E (1-0) v H (1-0)::: E wins
B (0-1) v C (0-1)::: B wins
F (0-1) v G (0-1)::: G wins

Round 3
D (2-0) v E (2-0)::: D wins
A (1-1) v H (1-1)::: A wins (I couldn’t put A v B here because A & B already played each other)
B (1-1) v G (1-1)::: B wins (I couldn’t put HvG here for the same reason)
C (0-2) v F (0-2)::: C wins

Final Standings
1. D (WWW)
2. E (WWL)
3. A (WLW)
4. B (LWW)
5. H (WLL)
6. G (LWL)
7. C (LLW)
8. F (LLL)

Tiebreaks: The better your record is, the stronger your opposition will be. That’s why ppl who start strong and lose late are seeded above ppl who start poorly and puff their record up against weaker foes.

Bracket:
Seed 1 plays an (0-3) team from another pool
Seeds 2-4 play teams with a (1-2) records from other pools
Seeds 5-7 play teams with a (2-1) records from other pools
Seed 8 plays a (3-0) team from another pool

the order in which you win pools matches shouldn't matter

why should WLW be below WWL? the both went 2-1, and that's what counts
WWL>WLW because WWL beat a 1-0. WLW only beat someone who went 1-1. Even if both people lost to the same person. The WLW wins aren't as high in quality as the WWL because of that.

It is inherent in the system.

What would be the best way to randomize who plays who?
if you have a rankings system,

best player 5th best
2nd best 6th best
3rd best 7th best
4th best 8th best

but it doesn't really matter.

or if you mean seperating into pools, I just put all the names in a hat and roll with it.

Well I tend to get a lot of **** from my players over the stupidest things. I don't want to have to balance the games at each round of pools.

I think how i'm going to do it is assign each player in the pool a number then roll a die to match players up.

that would work.
doing this for smash is so much easier than chess...
