On the CFM A319 that I fly the stabilised Flap FULL/Vapp total fuel flow is normally 30-32kgs/min. and Flap3/Vapp gives 26-28kgs/min.
With decellerated approach techniques normally one is only fully spooled up from 1000ft. AAL. - so the question remains - where does your 75kgs /landing come from?!!
