Hi Derwin, Your spreadsheets is so helpful! I have not gone through it entirely but happened to make an observation.
Suppose we consider as per defaults in the spreadsheet,that is ly/lx=1.6, and this is for panel type 9. The BS code allows for interpolation and i would think that the coefficient for the above(shorter span) would lie in between 0.092( for ly/lx=1.5) and 0.103(for ly/lx=1.75), say taking up a value of 0.0964 to be exact, and not 0.103 as per the spreadsheet. Did you take this into consideration and opted for the higher side without interpolation, thus being conservative?
