Thank you Cecil for the reply, I will apply the Grand Duke Theory when doing minor repairs or spot repairs to certain sections of my house. However, this theory doesn't seem too practical if one has to do Major renovations to one's house because there will always be 2 directions (the one in Conflict and the one where the Grand Duke is located) that will cause bad luck. For example, if I was to replace my entire roof this March, it would be impractical to not replace the South and North section of the roof while replacing the other directions. Likewise if I purchased a new home and wanted to fix it up before moving in, such as painting the interior and exterior and changing to new carpets, it would not be practical to do only 6 directions and not the 2. So it seems to me that the application of this theory makes sense if only spot repairs or renovations that do not involve the whole house are done.
