I was taught this for killing sentry's as a part of a BBD Ninjutsu (Ninja) training course a few years back. It did not seem to make a difference at the time. But it did make me wonderer if the chances of being noticed by a sixth sense increased when the intent to kill or harm is real, rather than just as part of training.
