ETF2L – Latest activity in “[ETF2L] Swiss Style Tournament System” https://staging.etf2l.org/forum/feedback/topic-30613/ Reply by dnscodcs https://staging.etf2l.org/forum/feedback/topic-30613/page-9/?recent=528828#post=528828 Quoted from Permzilla
[...] Actually I don't think thats possible due to the way fixtures are matched, teams above them are matched together and at least 1 of them is guaranteed to get 3 points per match. So even if they win their remaining games (29 points) Lemmings vs Gamsjaga is a fixture so at minimum one of these teams will have 30 afterwards. I'm sure there are other fixtures which push teams over that too. The logic is there but I'd hazard a rough guess that no one below 8th can place 1st anymore.
I didn't say that they could place first and have the most points, just that they had a chance of overtaking the current top team in points and making it to the playoffs. (For that to work the results would have to be lemmings lose lose and back of the net win win to have a final point score of 27 to 29 in favor of BOTN between the two teams)]]> generator=rsdiscuss&baseurl=https://staging.etf2l.org&feed=forum&forum=feedback&topic=30613&post=528828 Sun, 08 Mar 2015 17:06:43 +0100 Reply by Permzilla https://staging.etf2l.org/forum/feedback/topic-30613/page-9/?recent=528828#post=528824 Quoted from ducky
To give you an example out of the running season: In mid-tier a rather mediocre team such as UnitedKingdom Bantermory sponsored by Sony DADC (27th) can still go ahead, overtake the currently highest placed team Germany Lemmings in points , get to playoffs and become Mid-Champions , depending on how each team in that tier performs in their future officials. It's rather unlikely, but still within the realms of possibility. *wink* *wink*

It's an interesting system. Can we see the actual pairing algorithm?
If you're referring to the actual code you'll have to ask emb, if you just want to know the system, well: Pick the top team of any tier, look at their previous matches and who they've been matched against for this week. It should be pretty obvious how it works.
Will you use Gibsonisation in the last round?
I take it that with "round" you're referring to the last week of the season? As for potentially applying the gibson rule: Very very unlikely to happen in this league. Since we've been using the swiss system the tier-winner of a season is no longer determined by the amount of points that they've accumulated throughout the competition , at least not directly. These points merely determine a teams' eligiblity to continue to the playoffs, where they might provide the top teams with a minimal advantage by giving them a higher seed (if you consider that an advantage that is). Adding to that an ETF2L season is very "comeback friendly".

When a team doesn't play a week how do you decide how many points they should get?

Q: What happens if there is an odd number of teams in my Tier? A: Currently if there are an odd number of teams, the team in the middle position of the Tier will receive a ‘bye’ which will award them the full 6 points but with no fixture for that week. Teams are only eligible to receive at maximum 1 bye each Season. We are looking at implementing a system which will prioritize teams that received default losses in the previous week to get a bye, but for now it will be the middle team.

Maybe they've given up on not playing teams twice, Gentleman Jon said it would get a bit weird.
I remember some teams' week 2 or 3 fixtures were against the team they've already played, but this was fixed later on.]]> generator=rsdiscuss&baseurl=https://staging.etf2l.org&feed=forum&forum=feedback&topic=30613&post=528132 Sun, 01 Mar 2015 12:48:21 +0100 Reply by fraac https://staging.etf2l.org/forum/feedback/topic-30613/page-8/?recent=528828#post=528131 generator=rsdiscuss&baseurl=https://staging.etf2l.org&feed=forum&forum=feedback&topic=30613&post=528131 Sun, 01 Mar 2015 12:37:00 +0100 Reply by W.

I don't know how sophisticated the system that creates match fixtures is but currently there are 38 teams in open with 2-4 record (also 37 teams with 4-2 record). If I've understood correctly how the fixtures are picked then the system randomly matches these 38 teams against each other.
There were some 'virtual' points earlier on that made it a bit unclear but they disappear at some point (already gone I think), then it's only 4-2 teams against other 4-2 teams and 2-4 teams against other 2-4 teams, with exceptions for teams with unusual records with no matching opponent or who have already played the only qualifying opponent. There may be some luck, getting your good maps at the right time for example, but it will even out. By the end of the 8 games your position will be fair. If you're worried about whether a handful of positions in mid table are 100% accurate, they may not be but in the old system there was simply no representation of a middle placed team's level at all. Open is definitely not too large, to work out the appropriate number of Swiss rounds for a group you take the log 2 of the total number of teams rounded up. Even with 200 teams 8 rounds is fine. It may be made muddier by things like the golden cap rules, but those are compensated for by the accelerated pairings.]]> generator=rsdiscuss&baseurl=https://staging.etf2l.org&feed=forum&forum=feedback&topic=30613&post=527744 Tue, 24 Feb 2015 15:03:48 +0100
