There's more to it than your easy fix, the article alludes to it but does a poor job of covering it: if you know the distributions of the intermediate steps, but you only sum the means of the steps, then you are throwing away data that could help you calculate a better estimate.

I just found it very strange that the core assumption of the article -- that the default setting is to add median times of subtasks -- was never questioned. Why was that the chosen method to begin with? Most time estimating tools (Pivotal Tracker, etc.) work with averages, not medians, for precisely this reason.
