Adjusting and mapping would be an easy course of action, I will admit. I'm just a technical person who likes to know why something works the way it does.
By adjusting and measuring the results I am in essence creating the same thing as a polar gain plot. I haven't put myself into a situation where adjusting my antenna is too difficult, I just don't like ladders and heights!(And it's Buffalo and winter, not always the best mix
) I would rather change the position to the most practical spot the first time.
