ObiWan - anything you can share is useful, especially at your squad's level and with the high differences in Base Score that you're seeing. I can document data every 2 days but it isn't going to help figure out the wonky high level matchups (at least not for a while). I think it's safe to say that only War Party info matters, I just figured I'd document whole Squad's info just in case. I think the numbers that matter are Avg War Party Base Score, Avg War Party Adjusted Base Score and Matchmaking Time.
Two main goals with comparing data:
1) Is War MM based just on Base Scores or Adjusted Base Scores to factor in medals? This should be easy to nail down.
2) Does the MM algorithm start by looking for close matchups (+/-5%) and then continue to expand the range it searches as time goes on (up to +/-30% that you are seeing, or further)? If strength variance is time based, maybe we can determine the time intervals and we can advise people to cancel long running MM after a certain time.
We only got a very brief War MM explanation near the end of the Playdom forum and it may have changed since then. Anything we can do to better understand the game is just going to make it a better experience.
