This ladder system was created after test running an ELO ladder which had a hard time dealing with a lack of data, and mid-level clans winning significantly over newer clans which led to some skewed results.

How this Version Works:

- Once a clan challenge is completed, it is added to the database (Excel File)
- Using some complex calculations and look-ups, it calculates out Win Percentage (WP), Opponent's Win Percentage (OWP) and Opponent's Opponent's Win Percentage (OOWP), and the Reliability Factor (RF). (See below for Factor rates)
- An RPI is generated for each team, generally between 1.00 and 2.00 using RPI = [(WP + OWP + OOWP) * RF]
- Based on all the RPI's, they are all scaled up to a Grading out of 100 with the top Clan at a 100 Rating

Reliability Factors:

- 0.00 if your clan is extinct
- 0.80 for 1 completed challenge
- 0.85 for 2 challenges
- 0.90 for 3 completed challenges and less than 61 total games
- 1.00 for 3 completed challenges and more than 60 total games
