I can supply
I have a set of "norms" for the 744. I can distill these into a spreasheet quite easily.
For the a/c I know a look out the window, figures from the loadsheet and put the two together. Bingo. Yes, you do need some kind of ready reckoner in case one day the gremlin strikes.
I don't need to rehearse the usual caveats. If this will do either post or drop me a line.
