i never really totally understood the whole sales thing anyway. i can understand that it shuts up people that don't really want to reveal they are full of it, and make no sales here at all. but at the same time if you sell your own work to yourself, buying it for yourself, your numbers will go up. and its an average, so you may do very well one month and the rest is nothing. and it was simply a coincidence you did well.
i think in the end a newbie will just want to know what the advice is, even if its just passed on by someone that does sell well, and don't care so much that you only average a certain amount a month. or maybe its harmful to the site, where knowing that everyone that answered for the most part only make 4 sales a month, the newbie will assume the number should be a lot higher.
