I think the forum games thing has only been noticed like twice since I implemented it.

So if you make a new account, then post twice in one day, then come back like a year later, and post twice in a day again, then your posts per day is still at 2. Thus, it doesn't decrease the percentage if you don't post at all one day.
I think it's more postcount/(days since you've registered), since that would be a lot easier on the database.
