Think about the odds of two different people in the world, with different physical copies of the CD, different computers, different drives, etc. getting the exact same rip. You might say, what if the other person has an error and your rip matches that error. Again, what are the odds of two people getting ripping errors with the exact same frames. Essentially impossible. Note that an AR match of only 1, may not be as informative, but only in the case where you have ripped the CD before in a program that submits it to the AR database. So in this case, your AR of 1 could be matching against your old AR submission. That's why an AR(2) is better. Then again, this AR(1) issue is not a problem if you've never ripped your CD before. In this case, an AR(1) is also evidence that you got a perfect rip.
