I might be missing the point here (wouldnt be the first time either) but why is there a pressure to uplift less fuel for a leg, if the fuel you don't use will only be used for the next leg?
I realise this might seem too simplistic but surely if you lift say 15% more than you need and don't use it, it doesn't go anywhere, it simply gets integrated into the next leg calculation and used there, hence that leg will have less of an uplift than it normally would. Since its all from the same company coffers, surley it all evens out? This would cater for the holds, unforseen headwinds etc which would and will happen anyways. Just means you wouldn't have to divert and upset all your pax. Again sorry if I'm missing the point here.
The only time you have too much fuel is when you're fire.
