By these criteria the "lovely gammas" W hypothesis looks increasingly unlikely to me as its experimental effects get less definite and more complex. That negative factor (over-complex fit to experiment) is now large.
As a skeptic, for various reasons, I did not much like it initially. Others could have had a much higher estimate of it at that time. Now, as the "lovely gamma" behaviour reveals itself as weirder and weirder, when fitted to the W hypothesis, the W hypothesis looks less likely than it did a few pages back; independent of initial estimates.
I very well understand that "lovely gammas" are not a physical description and I would never use such a term in a paper. Thus it is rational that simple bloggers with no theoretical background get confused by wild terms...
The history of the "lovely gammas" is very simple: A well running experiment with a varying high COP turned mad during the diurnal phase and emitted about 100 times background gammas.
The suspect particle causing the effect is most likely a relativistic positronium. The dual flux nature of this particle makes it ideal for a 4D symmetric stimulation/coupling to an existing strong LENR field.
Our daily business, independent of external radiation, is LENR with excess heat in the range of 1-2 watts from 1g of fuel. This amount is quite handsome and easy to measure in a well insulated system. The gammas are always present and we also had one fuel that started gamma emission without any heating!
If the new model is right then the delta E of a "deep magnetic state" and normal deuterium ground state is close to nothing. The only problem is to bring the electron down into a 4D magnetic orbit what needs a little bit more than just super-wave stimulation. Some call the acting agent catalyst as there is a kind potential barrier. But as Holmlid said: Turning on the lab light was sometimes enough.
The nice thing about this fact is that LENR is everywhere and it's the normal way nature works. This is the worst what could happen to standard fantasy physics and ITER.
