RPM alone doesn't mean an engine is loaded or not, after all the highest rpm you can reach is high idle and that is obtained with no load.
Overload is defined by the power output at a given rpm, look at the propeller curve, not just the tach alone. After all, isn't that what you are doing when you promote the idea of a "cruise prop?"
