On this very topic; it's interesting, my friend came over yesterday to help me work on my car. He is thinner than me on top and does nothing to conceal or hide his hairloss. He is not quite horseshoe bald but is very wispy on top and has nothing in front. The kicker, he has fully normal temple points. Thicker than mine and mine aren't so bad. He is Hispanic so I'm not sure if this makes a difference.

But the point being is that no two heads of hair are exactly alike and neither are the patterns of MPB all the same. I still sand by my statement that only a hair obsessed wig wearer would ever take note of such things and even then, due to hair pattern randomness, they would rarely if ever truly be able to guess correctly based on temple points alone.
