Well there might be something to it, apart from blue suede shoes. Looking at it from a fractal perspective, 2 data points is useless. That gives you a straight line, under any circumstances. 3 points is the minimum to construct a triangle, the most basic geometric shape, the most basic construct of comparison. They dont use two data points for triangulation in navigation, for example.
========== Good points; 20 can help with a trend also. Most of smaller fibo number come up/down more than random.
