And that is a significant part of your answer. HP is torque X RPM/52??. Anyway, RPM is a significant factor in achieving HP and you will not hit peak HP unless you are at peak RPM. Just to get some review, look at every HP graph, it is typically a fairly linear line that rises with RPM, until the torque drops off as the engine starves for air. Accuracy is going to be based on how efficient your engine is. The assumption is that you burn X amount of fuel, it will result in X amount of power output. The lack of efficiency is a result of if all the fuel burn all at once, or if some of it burns too late to do any good. It is somewhat predictable, so I would expect the scan gauge to be somewhat accurate.
