Another fact missed often in case of the L/G down mentioned above is the penalty algorithm.

It is penalty of 180 percent which comes on top of the normal burn.

Assuming normal FRF 1250 and ALTN fuel of 1750,

​​​​​​3 + 3 x 1.8 = 8.4 T.

If that was for G HYD LO PR with doors hanging, there's another +15% IIRC.
