".......compatible with the known surface temperature of the alumina (780C)."
780 degC??
And what would be wrong with the analysis of Bob Higgins, which concluded 1100 degC?

The only thing we can be certain of wrt the Lugano test is that the alumina surface temperature was not as high as 1400 degC.
But that does not mean that COP was lower than stated in the Lugano report. It could be even higher. Too many unkown parameters. Like energy spectrum of LENR and related alumina transmittance.
Use of IR thermal measurments is not suitable to evaluate energy released from LENR.
