Steve,
Thanks for showing me how stupid I am. All calculations were done in
x1000 and somewhere it wasn't working with the extensions that Cacti has
since it does some weird summation that can't be turned off, so I
switched to GPRINT and I don't know why that wasn't working with the
defaults .. but somewhere I had fixed it, but only after turning on the
"Multiply by 1024" option to change the display from M to G.
Calculations are x 1000, not 1024! I added an option to multiply by
1000 instead of 1024 and its now giving the right results. Its one of
those issues where I broke it in one place trying to fix it in another.
Don't know why I didn't see that the results were just over by that
little amount, but thanks for pointing that out!

I think your problem is defining how big 1GB actually is.
If the data you're feeding defines it as 1024 x 1024 x 1024 then it will be
larger than 1000 x 1000 x 1000, which is the way it will be defined by default.
Even worse you may be thinking of it as 1000 x 1000 K where 1K=1024...
When you call the RRD graph command, you can pass a parameter to specify how
big 1K is -- if you use 1024 then you'll get 1G as 1024x1024x1024 which will
likely give the value you expect.
