I have been postwhoring regularly, but my average daily post count remains the same.
It's because you've been here so long; it takes more to effect the average.
Kind of thought that was the reason
Yes, a day of 100 or more posts will only raise my average by about .01 because I've been here 3.5 years.
It's not how long you have been here, but how many posts you already have.
Had you been a once a month poster, a day of 100 or more posts would make a massive difference, even after a 7 year membership.
