Probable outcome -
(a) if your sums are set up correctly
(b) you designed and are the only user of the sheet
(c) the OEM calcs are called up in the approved loading system
then you are likely fine. I wouldn't bother printing it to hardcopy .. rather to file.
Not a significant concern but try plotting the fuel line for several points between ZFW and TO .. might be a little surprise there for you ..
