It seems like I am going to need to rate at least like 25 or 30 games in total just to be able to get 20 ratings: I don't know, it seems like there must be something going wrong with the algorithm here. I've seen other games that have a similar number of 'ratings given' and 'karma for feedback' as me (and more 'ratings received'!), that have a much larger smart balance. Is there something I'm missing?

For example, compare my scores to another game's scores:

They have drastically more smart balance, even though they have less ratings given, less karma, and more ratings received. (Not a knock on them, of course, I'm just confused about the algorithm here...)

Edited to add: I'm not particularly interested in how to get more ratings--I'm more interested in why is this smart balance so low. Lots of people do have nice advice on getting more ratings, but it doesn't really solve my problem.
