I am going to gain investment in a comparator to make seating depth easier because the tips of bullets have varied and is aggrevating a little.
For your AR I think you'll have to seat them to the depth that the magazine will accept them and call it good. I believe that is generally always a shorter OAL than what you found doing like the video showed or what NM447 and RR were talking about doing. If I'm wrong, I'm sure he will correct me. That video was for a bolt rifle and I missed the fact you had an AR.
