Sorry can't help you. The B744 I have fuelled have usually been around 125-130 tons of fuel. I set up 125T on the refuel panel and leave the stab switch off. I then come back towards the end and do the last bit manually. What I was always careful of was an initial figure of say 128T (no fuel in the stab) followed by a final figure of 132T (about 4 T in the stab) and you could get too much in the centre. But I usually asked the crew and they were always willing to put 132T with no stab fuel. OK as long as the dispatcher knows!
