Uses the RPI formulation of Win% (WP), Opponent's Win% (OWP) and Opponent's Opponent's Win% (OOWP) and then combined with a Strength of Schedule
A ladder contains all results for the last 2 years.
The A Ladder also includes Season 1 and Season 2 of the League (in total vs an opponent called Season 1), but is not included in the W-L-T record. The league is weighted less due to the amount of Doubles played in Season 1.
Most historical data is grandfathered. A ladder results need a minimum of 40 games
There is a Decay Factor which lessens the impact of older challenges. After 2 years, the factor is 0 and that challenge is removed from the database
The is also a Depth Factor. This factor places a higher weighting on larger challenges above the minimum game numbers.
I have added total Games to show the experience levels of clans
The A ladder has an additional factor call "Team Play". This factor is to promote a balance of Dubs-Trips-Quads. The target is an average of 2.85 to 3.15 players per game.
Ladder will be updated periodically and after significant challenges
I don't know how you did it JP, but that's a pretty damn good ladder. Although I think tofu is 3-0. Good ladder though. Nemesis and Kort are still undervalued, but after looking at the spread sheets myself, I amazed that you came up with something this good.
I won't argue, but this is on KORT actually getting challenges (against A clans) under their belt. They'll move up in time... but for now their only result against an A is a tie against the #10 clan in only 30 games. They are ranked right around where they should be based on completed results only. Remember that the rankings don't judge "talent", only results.

What happens if a B clan becomes and A clan? Will the challenge then affect the A ladder?
If a B rated Clan defeats or shows A level status in a challenge (>=40 games) against an A clan (aka qualifying challenge), that challenge and clan will be added to the A ladder results. All previous results of the promoted B clan do not transfer over.
There is some subjectivity here I realized, but it should work. I've also noted that if a clan falls below a 70 ranking, they are more likely a B clan. Hopefully B clans won't have to lobby on too many results. The next league will need to open up to opportunities and I have a plan.
surely one of the best, if not the best ladder jp has presented. great work mate, but you might consider removing A/B rated clans.
what interest me here is how is KoTR A rated clan? they have play only one challenge against A clans, and that challenge was 30 games tie? and as youve said "A ladder results need a minimum of 40 games", so if KoTR vs G1 was 30 games challenge, KoTR doesnt meets minimum requirements for being A rated clan.

The standard back then was 30 games, and was 20 in the past at some point. Going forward, I'm expecting A clans to play a minimum of 40 games, and the average is close to that.

If B Clan becomes A clan, none of the previous results transfer over?
So, AoC's challenge against EMPIRE would not transfer?
Also, I'd be interested in knowing what our A rank is (some number below 70), even though we are in B rank. If that's possible.
Nice job JP, well done (I thought you'd gone quiet for a while, now I know why).
Am I alone in thinking the results would look better written W-T-L (rather than W-L-T) as I find the losing result put in the centre is somewhat deceptive?
5-2-0 should be superior to 5-0-2, yet that's not how it appears. Small matter, but more aesthetically pleasing (and more logical). Thanks

I agree with KORT being undervalued....a few that are "A" clans I would disagree with...
Seems like this will be a good foundation for the future rankings to build from

(oh...and rank the clans based on Win %)
j/k
You crazy europeans and your soccer. jp was right in that its WLT in North America and WTL with you soccer hooligans. Just a matter of what you are used to.
Nice job on the ladder jp. And anyone who thinks they are undervalued could actually undergo a clan war sometime this year and prove it. (not pointing any fingers.. cough...KORT...cough)

Hey now, we haven't complained. The completion of season 2 of the league and the conqueror's cup should give us some more data!
Those guys (and gals?) are goooood.
highest score: 2157 (Major) / Verd ori'shya beskar'gam
