i don't understand the procedures you do. If you're going to land with <7t the fuel will have transferred whilst still mostly in the cruise/early descent. and why mess with the systems pages/ECAM on finals??? Quick look at the fuel page before the approach should tell you its all where you want it - in the inners and should be balanced from the earlier forward trim transfer. 7T in a 330 isn't all that bad if weather nice / close alternate / low weight etc etc
