While some people do hear much better than they receive all the time in all directions, and are a waste of transmitter power, the issue often involves more than just power levels.

Any analysis is flawed unless it considers TX antenna efficiency, QRM levels, as well as differences in patterns when split antennas (separate RX TX antennas) are being used. A big problem is getting operators to listen in other directions when using directional RX antennas.

Contests are especially a PITA so far as QRM on the eastern half of the USA, and I'm sure it is this way in Europe. All it takes is a wide signal 500 Hz or more away, or a weak local signal nearly on frequency, to kill someone's receiving.
