I interpret this as meaning the total messages of all members. As such, a member posting 100 messages and getting 20 +'s out of it would have the same rating as a member posting 20 messages and getting 20 +'s out of it.
It seems to me (someone who doesn't post many messages), that the individual's total messages over the last 90 days should also somehow be factored in.

Sorry, I see now that you'd have to read back a ways to see the context is messages for a member. The denominator used to be the total number of a member's messages that had received votes over the past 90 days . Now the denominator is the total number of a member's messages over the past 90 days.
