Yes, I agree. The more and more I look at it, I'm not convinced about the second method, either. At least not as exactly stated in this chart. First of all, you about need an assistant to really do it correctly. I think I used a Stanley tape measure extended out and just kind of eyeballed it from afar. But secondly, I'm looking at the marks on the diagram of the foot, and it doesn't make any sense to me. I think the first measurement is too far up on the toes and the second is too far back on the heel, giving an artificially high number. Thirdly, it doesn't take into account toe flexibility, which is kind of important once you reach towering heights. I'm hoping, as are the rest of the participants in this thread, that your actual ideal heel height can be increased with practice and the force of will.
