An easy way to max out area-under-the curve is to select an RPM range you'd like to max out. In a given gear you'd go from a particular speed/RPM to another speed/RPM. Combos that do this in the least elapsed time for comparable hp/torque curve shapes have the most a-u-t-curve.
If you can you measure the actual distance required to make that speed/RPM change. Least distance covered while doing that = most a-u-t-c and is what we really want - to be ahead of the other guy. That evens things out for cars with grossly different curve shapes. It's easy to do stuff like that with an AP22 fpr example. On my M3 a particular ignition wire seems to save 2-3 feet on a 15-60 MPH run in 2nd gear. So if you had two identical cars running side by side one would gain a fender on the other in that instance. Yet it may not have the highest HP.
