Jed,
Without seeing a lot more heat data, I have to agree, it is difficult to
derive any meaning from this and that there is, as you say, "practically no
real-time correlation to the helium." We also are missing a lot of
information about their method of helium sampling.

I think that is clearer. You can see that the power levels are really not
that varied, and there is practically no real-time correlation to the
helium. Actually, the error bars are probably even larger because the
instrument is at the limits of detection. At higher levels both accuracy
and precision improve. That's true of most instruments. Plus, I have no
doubt the helium levels really do vary, and this is not just an instrument
artifact, for the reasons given in the document: different amounts of
helium are captured in the near surface layers of the metal, depending on
complex factors. That is well established. You have to go to great lengths
to recover all of the helium. During the run the stuff will suddenly vent
at odd times, presumably when a crack forms.
This is how marginal experimental data looks. If the correlation was
better than this I would begin to suspect someone doctored the data. With
an instrument that can detect 1 ppb minimum, the difference between 1 and
3 ppb is hardly meaningful. On the other hand the difference between 100
ppb and 101 ppb is more significant and reliable.

Also bear in mind those are instantaneous power levels, and there is no
telling what it was doing in the instant before they were taken. For
example, data point #2, 11-29-93 is 35 mW. It might have been 50 mW
sometime earlier, which would explain why there is more helium in the cell
than there was with data point #1 even though the power level is the same.
Cold fusion power does not fluctuate wildly, but it does fluctuate. Also,
as I said, the helium you measure at any given moment might have been
generated hours or days before, and it is just escaping now through a
newly opened crack.
You need much higher, more steady power to establish the ratio of helium
to heat more accurately.
