Adjusting the truss rod is completely overthought, just like guitar humidity. It's really a simple adjustment that accomplishes a simple task and is dirt easy, when done with a little care. Maybe I'm just old and it's lost its perplexity, but it's just a part of owning a guitar and is not that big a deal. Like changing the oil on your car, the first couple of times you try it may be intimidating, but then it becomes second nature.
