Just a suggestion
When the fuel figures are sent back by acars, additional info of Rwy in use/OAT/Surface wind could easily allow some gross error check figures to be added to the loadsheet.
In fact, they could relatively easily add the whole set of figures which would be even better.
However, in the interests of time/money etc, a flex and green dot would suffice.
It shouldn't be difficult to do, they have the software already.
If some rocket surgeon posted this weeks ago, my apologies, too much to read now.
