Each clans record will be reset each round yet they will keep an overall record as well. Any clan that joins after week#8 of the current season, will be placed at bottom of ladder and will not have a chance for that seasons Champion Ship Tournament. Clans will however start acumulating an overall record and placing themselves for the next season rankings.
There are a couple factors that are used to figure out which teams should play each other. I will list these in order that they should be applied.
1. Most important is that they haven't played each other in the last 5 weeks. This is counting bye weeks. This does not count weeks where the league was suspended due to some unforseen problem (like a new patch or a holiday etc etc)
2. Streak: Teams that are on a hot streak should play each other. Teams that are not doing too well should also play each other. If you don't have two teams that have the same streak, say you don't have two 3W teams. 3W playing a 1W is much better than a 3W playing a 2L. We try to get the streaks as close together as possible.
3. +/- is the final criteria. WE try to have clans battle that are in similar places ranking wise. This is only if criteria 1 and 2 have been met. It's no biggy to have somone at the top play someone at the bottom if their streaks are close.
Rankings:
Rankings are done like so: First criteria is the current season record. A 5-0 clan would be ranked higher than a 5-2 clan. This should also coinside with +/-. This is figured by how many games over or under .500 you are. So a 10-5 team is +5. A 2-3 team is -1. The streak is incremented by one each week. Win % is calculated by wins divided by Total Matches rounded to THREE decimal places. So it's .500 not .5. So a 10-5 record would be figured as 10 wins divided by 15 matches = the winning %. In this case it would be .667%
