since the object is to minimize the time in which this work is accomplished, we must maximize power. work / time is the very definition of power. shift points should be chosen in such a way as to maximize average power AT THE WHEELS. this is why blue2K is correct in stating that the curves alone will not tell us the best shift points; gearing must be considered. the car with the highest average horsepower AT THE WHEELS over a given distance wins the race.

100% in agreement. From the time it takes to move that distance, you'll get an average acceleration and know what the speed is at the end.
Just to add, not just gearing and torque must be considered, but also the vehicle speed in gear.
