Sorry I missed the cool down part. What was the power for 400C?
If it was 42W for 300C then the COP reached above 1.2 (compared to real calibration)
Please disregard what I've previously written. I just realized that I have probably used incorrect data for power data in the graphs I previously posted, so I'm now in the process of replotting it again. I got fooled by the (apparent?) lack of decimal digit precision of its values, and thought it was something else instead.
@me356: to be 100% sure, since I've been literally guessing what is what, could you write down what each column in the CSV files is actually representing, and preferably add this information in the files next time?
