Exactly, and consistent with what Mike just wrote and many other hams found, same as my own tests. Mike could not write clearer. Any low power complaint is related with low voltage arriving inside the radio when many amperes try to flow from power supply towards the final transistors. Wattmeters either internal or external are not the problem, some cannot measure PEP and none are accurate enough compared with the measuring systems available at the manufacturer calibration laboratory, but meters are not our problem. Getting 200w from a 200w radio is easy because the radio was designed, built and calibrated to make the job. We can be sure that no low output problem is because the factory did the wrong calibration. We better get good cables, good fuse holder, and set our decent enough power supply to the highest voltage we can set, although under the maximum allowed which is 15,89 or 13.8+15%, do not forget that around 14.4V is normally the voltage of any 12V automobile when the engine is on. We should forget the old 13.8 number, the 12V nominal battery voltage, and set our power supply to at least 14,5 Volts. Power depends on voltage squared, so small changes in voltage affect highly the power. The higher the voltage arriving at the final transistors the higher the maximum output power will be, and the cleanest our signal will be for any power level we put out. Please do not ruin factory settings instead, only to splatter other hams. You do not like splatters nor do I. Please... Be a good neighbor!
