During the chase scene at the end, it is shown on one monitor that the THX budget is 3,410 units over the budget of 14,000 units (24%). A voice had stated earlier that accounts are to be terminated when they exceed their original budget by 5%. When the account/chase is terminated, we hear a voice say that the THX project is 6% over budget, which would be 840 units, not 3,410.
