AVP is about being picky, if you're not interested in being picky AVP isn't the place for you. It's not just obvious, it's a repetition (like "PIN number").
This is (for those who don't know) an example of tautology. It indicates the speaker isn't in control of what they're saying, or hasn't prepared what they are going to say. It may be excusable in speech, but it don't make it right! Americans typically suffer from this, putting in a load of extra words in an attempt to sound more impressive - eg "the 1960's time frame".
