This was pretty well summed up in this recent post reply, it should answer all your questions.
As time goes on and more data is avaiable I'm sure you will be fascinated by what you get back, please also remember that I don't think moderators are on duty after hours so if you have any other queries you 'may' have to wait till Monday.
Thanks for your post and welcome to the Community.
