Dear Master Cecil Lee, My apartment is on the 9th floor and my balcony faces a wider view, with more sunshine.As my actual front door is closed most of the time, hence Iam assuming that my flat's correct facing is at the balcony. I need to know where I shldstand to get the correct compass reading of the balcony. When I stand at the centre of the apartment , the compass reads SW3 (240)whereas if I stand at the centre of the living room, my compass reads SW1(210). So,it does affect the Flying Star charts, and I noticed there are a lot of differences between these 2 charts. Awaiting yr kind advise. Tks in advance. Anonymous.
