Counting Sacrament Attendance

I'm curious as to how other clerks count Sacrament attendance. I know that many clerks walk down the aisle to count, but I have always thought this was a little distracting, so I count from the back. I realize that I may miss some, so I usually add a few to the final number. Any thoughts on this?

I'd stand in back and count. I'd count one side, check the foyers and then count from the other side to check my number. I tried to know the families well enough so I knew how many were in the family. That way I'd catch the ones under the bench or below eye level. That worked pretty well and I didn't feel the need to artificially inflate the number. I might add if I knew someone was walking the halls or I had reasonable idea they were there, but not present when I made my count. I'd also add to it later, if I saw someone come in really late.

If you have built-in chapel cameras you can zoom and pan around the chapel to count (assuming you're not broadcasting the meeting).
