Continue this process through the entire RPM range until you find max HP; go a little beyond that...and call it a day. Since HP is a direct function of TQ and RPM, there's no point in pushing the motor much beyond the point where you found max HP.

That seems to be the description of a steady-state test. How long would that normally take? Not sure if they did that here. Note the acceleration time of 5.8 sec noted at the bottom of the sheet?
