Dominion Scavenger is Back

The online rankings site Dominion Scavenger (http://dominion.lauxnet.com/scavenger/) has been down for a little over a month now, but I've finally had the time to make the changes necessary to bring the site back up.

Basically I cache a lot more aggressively now, so instead of constantly trying to pull latest results from the live Dominion Online servers, I pull them every minute and cache everything so when individual people load pages it all just happens on my server and doesn't reach out to Dominion Online's servers, potentially overwhelming them. So results should be updated every minute on Scavenger now (both on the "Scavenger" page as well as the "Live Leaderboards" page). As a side note, I've expanded the live leaderboard page to be the top 500 instead of just the top 200 now (http://dominion.lauxnet.com/live_leaderboard/ - must be in top 550 to start the day to be eligible).

My life's been too busy the past month to work on any of the suggestions that I've gotten for the site (quite obviously, as I didn't even fix the site), but the next few things I will work on will likely be:
  • Fixing the mu/phi/levels graph
  • "Recent live leaderboards" - such as leaderboard based primarily/only on the last 30 days of results.

I've also had several offers of people offering their help to work on the site. While that isn't currently too easy (my dev environments/repository settings are not easy to replicate as of right now, and most people aren't Django developers, which is what the site is written in), I want to make that more possible than it is right now, so I have a goal to make that better.

Thanks for the work on this, happy to see it's back!

Question about Glicko ratings (possible bug report?) while you're here:  Are there any circumstances under which a player's mu parameter should decrease after a win?

My match history currently looks like this.  The bottom line surprises me; I was under the impression that a win would always increase your mu (the algorithm's "best guess" about your true skill), and that even if your opponent was rated substantially lower, that would only result in a smaller increase in mu.  Have I misunderstood the rating system, or is this possibly a bug?

(Note that I don't specifically remember the game, so even if it is a bug, it could be a display bug rather than an actual ratings implementation bug; that is, maybe the bug is just that a loss is displaying as a win.)

The mu and other information listed with the games is for that opponent.

In the screenshot it shows that you won 4 games to an expected 3.5 and correspondingly your mu is projected to go up.

Can you unpack this more for me?  Does that mean that the negative number I was pointing out in the mu column doesn't mean "your mu decreased this match", but "this opponent's mu was lower than yours"?

Does that mean the other 3 players I beat has higher mu than me (despite being lower level)?

The mu in the column is the opponent's rating. The only thing that is affected by your rating is the expected win rate.

As someone who doesn't play online... can Scavenger show information about individual games? Or does it only do rankings?

Is this the difference between the Woodcutter tool and the Scavenger tool?

Scavanger shows player names, their ratings parameters, the result and the game number.
It doesn't show kingdom or deck composition over time as the Woodcutter tool.
