Whether it is 5 like he said it was in the original post or 30, it is flat out not enough data to make a projection for the year.
It's 30 days. I'm writing the GoogleDoc ( https://docs.google.com/spreadsheet/ccc?key=0AioqMMSVIC5tdFplWndsdmZuaGxyN01xemxtNWYxVGc#gid=0 )
The mcxFEE exist since less than 2 month so it's hard to do better estimation. You do with what you have.
But the October month was not particularly extraordinary, i don't see why the performance could not been reproduce in November.
The estimation is probably lower than the reality because Gaming will come in November on the site.
