Friction losses, the sun heating one side more then the other, the wind (if any) hitting one opening more then the other. If this is the only way you have @ your disposal, take an average, and cross your fingers. I built my home in Hawaii, using this method, and it was off. My last home was built using hired experts with laser levels, and it was off. Some times I think the earth, occasionally, just sucks a little harder in some spots.
