Bruce, you method sound remarkably similar to mine.
I just bear left on all rooms, doors and eventually cover all the rooms on each level.
I think the key is just to have a system and stick to it. I always find I miss things when things interrupt the flow whether it is realtors, leaks, dogs or weather. I do alter when I do the roof and attic according to the season and what time of day I'm at the house. Early in the morning in the summer, the roof and attic are toward the beginning of the inspection while later in the day and they are the last. Crawl space and lawn sprinklers are always last since I get dirty and wet.
