Using a newly understood geometric method we find that the observed scaling with N saturates at around N=7000 or even higher. In light of this new finding we withdraw the paper and will submit a revised manuscript reflecting our new understanding.WithdrawnQuantum PhysicsOther Condensed MatterGaussian number-squeezed states for sub-shot-noise interferometery in double-well Bose-Einstein condensatestext
