Perhaps you just misinterpret what he said. It could also be taken to mean:- "the output varied between 2.5 and 3.7 kW" rather than that there was a large error in the measurement. Note that specifying an output power to two significant digits implies that the error was +- 5 in the third digit.

If I did a study and came up with an answer >somewhere between 2.5 and 3.7 kW I would not publish it. That is an >absurdly wide error margin. Narrowing it down in this case is easy. It is >trivial. You calibrate. You step the cell through 8 or 10 steps at power >levels ranging from 4 to 8 kW. That range covers the lowest to the highest >power levels you think the cell is producing.
