It's total messages over the last 90 days.
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.
