Yeah man, they have a reputation for doing that. Unfortunately, they can be very accurate if calibrated correctly. They can actually measure the load from your car. Like Dynojets for example use engine RPM to calculate it. Don't know how, or if thats valid, just what I've heard.
25% drivetrain loss seems a little too much.. I hope the guy operating it was experienced with it and it's calibrations.
