This is bad news. It would explain why they have been testing wires for weeks now without seeing significant excess heat. I have heard also that Celani was unable to make his cell self sustain even though he increased the insulation. If he is making a mistake in calorimetry that would explain everything.
His method is crude. As I said during ICCF17, McKubre and others expressed doubts about it. I am not saying it is wrong for sure, but this certainly calls the results into question. This demonstrates why it is essential that all claims be tested independently, with different instruments. I expect the HUG instruments are better than Celani's. I wonder what the MFM will do next if this turns out to be a mistake. I have doubts about the calorimetry in some other gas loading claims claims, such as Takahashi, Kitamura et al.: http://lenr-canr.org/acrobat/TakahashiAphenomenol.pdf In my opinion, the reaction is too small and it does not continue long enough to be definitive. I think they are not using enough powder. - Jed
