Performance based on which CofG?

Hi,

I have this very silly question: Where can i find documentation on which C of G performance is based on?

My assumption is that it is based on worst case scenario, max fwd C of G. T/O and LDG are affected by longer rwy requirements, cruise by higher fuel flow, so it ought to be worst case scenario, right?

I have tried googling and search func here on pprune, but i am probably searching for the wrong keywords. I assume that the answers can be found in FAR/CS23 and CS/FAR25, but cant find it

A different question: On an average aircraft, how much does C of G affect the fuel flow and max weights? AFAIR, the 737-500 had a higher Perf based max landing mass when using aft C of G with the short field kit (never flew 737, that was back in my red cap days).
