Specifications should be accurate. Car manufacturers can't get away with advertising fuel efficiency of 50 mpg and not mentioning speed is only 20 mph. That's crap! The charge controller manufacturers are counting on the average person not able to interpret the spec correctly.

All of the information you want is there in the efficiency graphs. When peak efficiencies are mentioned, that's exactly what they mean: PEAK. It's not an evil plot to deceive customers; it's an attempt at being concise and trying to give an example of the best the controller can do. Refer to graphs for further details. Most people are quite able to interpret a line graph.
