Lol, you may be right. Problem is I suck ass at it. It is only by a stroke of luck that I hit the right note, so it feels like a gamble. Examine it too much, and you get yourself confused. I often act upon the wrong feeling because the original feels improbable/impossible/too good to be true or I just randomly pick and hope it's the right choice. But most likely some people are better at recognizing the right feeling, so it could possibly be a very effective tool if you are good at identifying it.
