Hacker/Excel Spread Sheet

I do want to say that I have finally finished making my system somewhat 
hacker proof...

Use two computers...Just keep your personal files on the one that will 
NEVER see the web.

Anyway, Here is an "On Topic" question:

I have FB2DV1-1.xls (from www.FullThrust.net).	This thing is really 
cool! :-)

Suppose I am designing a human ship.  Say it has a Class 2 beam.  In the

box labeled "X-arcs" do I put the amount of extra mass the extra arcs 
require, or the number of extra facings?

When I tried to enter some of the FB1 ships, my totals don't seem to 
match up with the book's.
I think this is my fault -- not entering the info correctly...I think I 
have all the book updates.

Now all this thing needs is a way to print out, or save, either a ship 
display, or a ship paragraph.
