Justin answers that question in one of the Q&A vids,
Though I could well be wrong and it's worth checking the vids to make sure, besides there's lots of useful info in them, your bound to learn some new stuff

I see that Justin confirmed you are right Fuzzel.
I would like to see the videos you mention, for the useful info you mention. Can you post links please? I keep reading about Q&A videos, and I would like to watch them, but I do not see them on the Lesson Index.
