When measuring and setting polarity
The closer a facing is to the 97.5° or 112.5° boundary, the more easily a measuring error pushes it into Mao 卯 or Chen 辰. When a reading falls within 1° of either boundary, measure again at several points before setting polarity.
Once polarity is set, every room, door or item lying within the 97.5° – 112.5° sector, seen from the center of the house, belongs to Yi.

Questions about Yi
Is a house facing 105° a East-facing house?
Yes, but that is not precise enough. The East spans 45° (67.5° – 112.5°) and holds three mountains, Jia, Mao, Yi; a house facing 105° is in Yi. Naming the mountain tells apart houses only a few degrees from each other.
What does a house facing Yi sit on?
It sits Xin 辛, 277.5° – 292.5°. Sitting and facing are always exactly 180° apart.
