I don't count them. But from long experience I know the most staircase have an odd number of stairs. My first step is "short" and whenever possible all following "long". That usually works. But to the current day I don't know whether there is a real reason to this observation. Maybe it's pure coincidence. Or maybe something typical to may country. Or after all it has indeed some real (maybe even wired) reason.
