You only need to put stuff in the total, A, Int, and High Value. However in the end it doesn't matter if you only put the total pieces in and left everything else blank. The other are there to keep track of what you need to take of the car when you get back to the building. If you can keep track of the Air, Int, and high vales you pick up and remove them from the car when you get back to the building without looking at the totals for each in the DIAD it doesn't matter. The only time allowances are when you pick bulk stops otherwise there really isn't any.
