"Thanks for the effort Ghostmaker - prety cool. I would also like to know how you calculate it.
Here are some intersting datapoints:
Average rating = 99.17
Median rating = 95
playing one game and being defeated gets you a 95
2 games with a defeat and a survive, gets you 100
kestasjk has played 75 games and won 7 of them, his rating is 76
Qing Shi Hwang has played 88 games and has been defeated in 84 of them (damn!!) rating = 0
AmestrisState has only played one game, in which he went CD, and his rating is 106
keeper0018 has played the most games on the site at 201 and he's won 20 of those, yet his rating is only 84
it doesn't appear to be rating you versus who you've played, but it does look like SCs are important"
Average rating- it should in theory be 100, but there is a rough edge at the moment which means that in a PPSC game where fewer than 34 centres are owned, in particular including CD Germany and Italy as unowned, there is a small deflation. A proper installation of an automated process would not have this defect.
Median rating<Average rating indicates a negative skew.
Loosing one game gives you 94-6 if against roughly average standard opponents.
Amestris benefits from another rough edge- I haven't added in that you get nothing if in CD, no matter what.
With keeper- Ghost-rating measures, or aims to measure, quality.
Who you play does matter alot, but because most games are PPSC, Centres normally matter obviously.
