Something I overlooked until about 8 years ago: 1.2 x AREA USED--- Example 1500 SF- min. length 46.5', maybe 4 heads---- 1590 SF- min. length 48', maybe 5 heads!

You must measure actual floor area with no regard to sprinkler spacing or distance to wall. Now in defining the area of coverage for each sprinkler, your question raises a point often asked. In a non-symmetrical layout, you use the longer on each side to define S and L such that the sprinkler is always in the center of the imaginary box. Not well explained by the standard since it mainly talks about distance to walls.
