Flying Chart Period

Question: How long does a flying chart is in effect ?
Meaning that the flying chart that your program constructed, is it good for this year and next year I would need to plan for a new chart since the "star" move around.
What is the effect when the "star" move around ? Or may be I should ask should we be concern with the reading of "flying star" movement monthly, yearly or every 20 years ?

The flying star chart that is generated for is a 20-year char which last from 1984 to 2003. However, if the house is not renovated in anyway after 2003, the chart is still valid.

When the stars move around, the feng shui will change. Thus, there is such a thing a yearly chart and even monthly chart. These report will be available at a later time.

One point to note is that in the period 7, number 7 and the next number 8 is auspicious.
