Hi 4space!
I'm not sure I completely understand the question, but the reading at the front door would drive the feng shui mountain, which is apparently a Northeast 2. It sounds as if a pie chart might be the way to go for the gridding of the space, as it will adapt to the subtleties you are experiencing in the overall direcitonal orientation. Did you muscle test to see if that seems most appropriate?
All the best!
Wendy
