It's ok to point out a flaw in my argument without calling me a liar. I probably should have said 3x the scanning time, perhaps not total boarding time, I agree with that much. That said, if the person blocking your seating arrived on the plane 20 minutes later because scanning took an extra 20 minutes, that still means you were delayed 20 minutes + person blocking you. But I'd expect someone who flies from an airport smarter than everyone else in the US to have already factored that in.
