Next he sized me up for my draw length, he had me put my fist on the wall and pull my other hand back to my face, he measured and said I'm a 27" draw. I thought this method was full of holes I could have bent my arm more or less, pulled my arm back more etc. I'm 6' tall and have a wingspan of 73". I was thinking the 28.5 or 29" range.I just looked at the bows and left.
I'm 6'1" with a 73" wingspan as well and I shoot 29.5" although I can shoot 30" pretty comfortably. (I used the same method you describe and came out with 30" even, 3x's in a row; trick is that you've got to sight down the tape with your dominant eye like you would look down an arrow shaft and keep your shoulders square as if you were executing proper form.)
