What is EIDRaS?
EIDRaS is an Elo like system for Diplomacy developed decades ago by some other people. Unfortunately, it's name is way worse than Ghost Rating. Check out these links for more information:

I made a slight tweak to some of the weightings to give smaller swings for provisional players (i.e. 7 games played or less). I found that it was going a little wild and giving some very new players some very high ratings.
How does it differ from Ghost Rating?
Tons of respect to The Ghost Maker for creating and maintaining a ratings system for us but it had several shortcomings. The part that bothered me most was that losses against expert opponents and beginners are rated equally. That is not the case for EIDRaS which calculates your expected score based on your opponents ratings. There are other differences too of course but that's the big one for me.
Some things I'm still working on:
- Dealing with non-WTA games
- Filtering inactive players
- Filtering banned players
- Adjust weighting for variants
- Make the spreadsheet prettier
Is there anything you guys want to see added?
VI, should I keep tweaking things until you overtake The Wiz and Nikola?
And a last minute warning to coders: please don't have aneurysm wading through my kiddie script.
