I was wondering if someone could explain the rationale/algorithm for the Geek Rating?

I am trying to understand at the gap between the user and geek ratings for MvM.

Not exactly, no, because it's kept secret to prevent manipulation.

It starts with a number of 5.5 (medium) ratings to prevent the designers' and playtesters' 10 ratings from pegging the Geek Rating.

Then it does some mathematical alchemy to reduce the effects of manipulative voting; I have my own ideas about how this is done, but the only person who can say is whoever coded it.

So, the Geek Rating will almost always be lower than the user average rating because of the initial 5.5 ratings. It will vary depending on the pattern of user rating because of the anti-manipulation function.

We've used the same system for something like ten years, so it's good to stay consistent so comparisons can be made. It's also good not to take ratings too seriously: a game you really like will always be rated low, and a game you dislike will always be rated too high. It's an average of what BGG users (who rate games) think.

Yes, basically it swings up as the number of votes increase.
(Or should I say it approaches the average rating)

I suppose it is possible to cross if a game has a lot of "manipulative" votes.

Top 1000! 11-29-2011 (or 29-11-2011 for you Euros out there) {2011-11-29 for Japanese}
I tracked the ranking for a while, compared to the number of votes. Until we lost some functionality/I got tired of it.

you can see how a game will have the average rating drop and the geek rating rise as they approach each other.
