There are a few typos etc, and the (long) section on "other errors" is maybe a bit ropey. But the 1.07 COP bit is pretty simple.
It is not a matter of belief - but of examining the math and the numerical calculation. I'll be happy to correct it if you find mistakes.
As stated in the Lagano report, when the temperature of the reactor was in the 1000C to 1100C range, the power supply was increased by slightly more than 100 W. The effect of raising power input was an increase in power emission of about 700 W.
Such a measurment is a realitive power measurment not subject to temperature calibation errors. In that high reactor temperature range, its COP was 7.
