While this does sound like a logical theorem I don't see why this would make a TSO be so actively against a person going through when it can be see done at various checkpoints. The lack of consistency just punches a hole in the thoery. Do you have inside info on this? if so..then awesome we have an answer.

Management at airports that have opt-outs go through the WTMD on their way to their patdown have to go through the added step of subtracting those opt-outs from the WTMD tally. It's just as simple as that.
