In a project I'm involved in there's an app (currently only for web) which is heavily gamification-centered. In this app users perform "bets" and are ranked according to "hit" percentages.
I'm looking for a ranking system which will normalize quite quickly, so the veteran user will have little or no advantage over the new ones.
Here are some of the things I've though about:
Percentages are not good here because in this specific application, a good player will normalize to about 70% "hits" - an unappealing figure.
Stars don't provide the level of granulation I need. I was hoping for at least 10-15 levels. 10-15 stars is unruly.
Discrete "titles" will require some code work to normalize, and are not immediately understandable.
Can anyone think of a better system to rank players by?
