Don't let yourself be pressurised.
The company I work for produces a league table about once a year. It's quite interesting to see how much fuel others (but no names given) carry back to home base. There is no pressure on individuals after the list is published, and even if there was I assume that anybody worth their salt would ignore it. Only the captain, on the day, can decide what is an acceptable fuel load for the flight.
I can't see any harm in any company giving you it's best estimate of ZFW. We get our ZFW on the cirrus flight plan just like BA, because we are a franchise that has eleected to use the FICO/sword/cirrus system. FICO doesn't appear to allow for number of children booked, which means that a school holiday flight to a holiday destination like Canaries will typically be 2 tons (out of 15 tons) lighter than the latest FICO prediction. So, it is quite normal to load less fuel than suggested on the Cirrus after a double check with the red cap in these exceptional circumstances. Surely it's part of good flight planning to obtain the best guess at ZFW, because the fuel burn depends on it - especially on long flights.
So, well done BA for trying to give an accurate ZFW. Pity that the atmosphere and culture of intimidation makes some nervous about carrying out their normal duties.
