In the level 4 course manual there is an example of taking a compass reading at the center of a home that is Southwest 2/3, period 8, with the compass reading indicating Southwest 2/3 and it appears the front door would be in the Southwest sector too.

If the front door is in the West sector and when standing at the front door the compass reading is still Southwest 2/3, period 8, when taking the reading from the center of the house do you measure the compass direction of the front door from the center of the house?

So when you are taking a compass reading from the center of the house what do you actually measure, the facing direction of the house, the compass direction of the front door from the center of the house or something else?

This doesn't appear to be clarified in the L4 course manual!
