New User Ratings #23

Hi Jose, Great job ! Am new to github so please pardon if this should not be reported as an issue but I just wanted to bring to your attention on the ratings that we are providing to the complete data for a new user.

The range for new user ratings seems to be [0,10] and when the reco engine makes predictions it throws predicted ratings in the similar range. Shouldn't it be in [0,5] range. When i supply ratings in this range it predicts movie ratings in the [0,5] range. But the predictions are drastically different than what they were earlier. Am i missing something here ?
