I think the fractal analogy nails it. Haven't thought about it before but I realize I too use a heuristic of x2 or x3 when estimating my time. Nothing would stop me from getting a pen and paper out and stepping through the 'trail' in my head in pseudocode beforehand, but for most of my projects I'd benefit from just writing the real code from the start and apply the time I saved to the project.
