That's your opinion. I don't know how extensively you have studied some of the less discussed replications. However, my opinion is that the fact that all of the alleged "black swans" combined provide robust and strong evidence for the "Rossi Effect" being real -- despite the characterization of the parameters needed to initialize the effect being almost non-existent. A simple combination of nickel powder and LiAlH4 seems to be capable of sporadically producing excess heat -- sometimes with no pre-processing of the fuel and no exotic electromagnetic stimulation. What makes many experiments totally unsuccessful is unknown. It's easy to proclaim that the nickel needs to be cleaned of oxides in order to absorb hydrogen, the nickel needs to be pre-heated to create microcavities, or a special waveform should be used. But excess heat has been reported without any of these.
If the excess heat reported by several teams of replicators is legitimate when we have little to no clue about the conditions required to trigger it, then I can only imagine the level of success that could be obtained if we knew what was actually important. The only thing preventing us from gathering that information is a lack of continued and on going testing. To me, it makes sense that two of the highest strung, work-a-holics who performed the most tests would figure it out, Me356 and Andrea Rossi.
