Does anyone know why?
It appears they tried loading it with pure H2 instead of an H2-Ar
mixture (75%-25%). This might (according to Dr.Celani) increase over
time the apparent excess heat.
According to MFMP calibrations with the inactive wire, at 1 bar of
pressure the wire should about 1°C hotter at the input power level
chosen (48 W), which means that their currently estimated excess heat
under pure H2 should be about 0.7 higher than under H2-Ar for this
reason alone. Anything significantly higher than this should be a due to
a genuine increase of temperatures due to a LENR effect or unknown
artifacts.
By the way, the controversy with "conservative baselines" arose because
the very first calibration performed with the inactive wire under H2-Ar
gas (thick blue line in the graph below) and the last ones performed
with the active wire under helium (not shown) showed significantly lower
external glass temperature readings than the rest of those made with the
inactive wire with different gases and pressures:

So, in order to avoid problems due to excess enthusiasm (my
interpretation) they chose as a baseline the calibration showing the
highest glass temperatures readings, which means that any possible
excess heat effect with the active wire under hydrogen atmosphere might
currently be significantly underestimated.
Of course, this is assuming that LENR is indeed occurring inside the
cell. There's still the chance that this could all be an unexpected
error artifact especially since they're measuring temperatures from a
more or less transparent glass tube.
