Could you provide your statistical analysis of the PdD2 CF results from1989- 2014, that justify this rather general statement THH?
Robert: I think you are making assumptions here. My general statement does not refer to any specific results, so could not be justified by reference to them.
However, your comment here provokes another general statement.
A statistical analysis of a set of results using differing methodologies, equipment, etc would not serve to determine whether a claimed effect was sporadic, because it might be perfectly replicable but only appear under particular (known) conditions.
To bring this to LENR specifics, Abd said a while ago that there was money for some guys to redo Pd/D2 work looking for correlation between excess heat and He. That set of experiments is to the point of your question, because if some controllable and replicable effect can be identified they could use it reliably in their experiments.
Quite apart from the correlation, their work would serve as an additional check on whether or not some replicable Pd/D effect exists, and analysis of their results would help determine the degree of replicability.
We are still not out of the woods on that, because as Shanahan has argued there could easily be a replicable effect based on some unexpected (by F&P. Jed, and those in the CF field) mechanism for ATER or another experimental lacuna that would in some experiments create apparent XSH anomalies that are in fact experimental anomalies.
The merit of new experimental work is that any such possibility, since it has been suggested, can relatively easily be checked and prevented in the new experiments. That would require them to read Shanahan's published work and explicitly guard against that possibility using better experimental design, rather than arguing on theoretical grounds that it could not happen as others have done. I'd expect that, from any competent group replicating the work, because Shanahan's CCS can be detected or evaded quite easily once you admit it as a possibility.
I have not heard the results of these experiments, but perhaps they now exist?
