granny fuel, you are talking about 100 to 200 kgs, if you are not happy with it make a LMC on the load sheet, but maybe just stupid thinking, you are planning
for a MTOW takeoff, fligh tplan fuel includes 300 kgs taxi fuel, but runway was changed and you need only 100 kgs for taxi. what you do you ask ATC to delay you takeoff to burn off the execssive fuel?
don't make things to complicated!
