You mention that we have 33% Heaven/Man/Earth "Luck" and then I notice while laying out the palaces, pretty much all of my apartment/house(technically an apt, but each apt is separate building) except 2 palaces is "bad" and I looked at other charts in period 7 and 8 to see what an optimal house facing chart would be and notice that they all have at least 4 bad palaces(for wealth, 3/5, health, 2 sitting, etc.) which takes the 33% down to what, like 10%?

 So, if my man luck is let's say at least 15%, and my Feng Shui luck is about 10%, then even if my Heaven luck is full 33%(which I'm sure it's not, so let's say at least 15%) or at least 15%, then I'm working with only 40% luck, or 55% if I fully optimize my "man luck."

 If this is the case in general, how is anyone supposed to get anywhere? Am I missing something in my calculations? It doesn't seem to make sense to me that you would only use like 2 or 3 rooms in a house just to not activate the annual and facing/sitting stars--what's the point of having a house at that point? (TL,DR:Feng Shui seems to have a minimal impact on your overall luck, limiting your use of your own house to 2 or 3 rooms, maybe 4 in most charts, so what's the point of having a house at all? (Am I figuring this wrong?) Thanks for your time.

Thanks for reading my book. But yes, you are indeed seeing this in the wrong perspective. 

You do not need to be so 'anal' about the percentages. They are merely a guide. It is not possible to precisely calculate the percentage of 'luck'. 

Like wise there are no 'completely good or bad rooms. Each room, with it's own Facing / Sitting stars, have positive and negative traits. As long as the stars fit YOUR GOAL, it can be considered a good room. 

For instance, you are in a Sitting Star #5 and Facing Star #1 room. Facing Star #1 is favorable for wealth. Using this as a study room (active room) is favorable because this utilizes the Facing Star #1. However, if you use this as a bedroom, you'd be using the "sitting star#5" and this would not be favorable. This is because bedrooms are considered YIN and the sitting star becomes the main focus. If you use this as STUDY ROOM, then it is an active room, the FACING STAR is the main focus. 

So every room can be "utilized" in a favorable way. 

Hope this helps. 

Warm Regards,
