Well, I have NO experience with eneloops - may try, someday, and may
even post the results here just to see what develops.
Each and every battery would behave in some particular way when
presented to some particular camera, in some specific temperature, after
X days of being charged by Z brand charger at Y volts versus A
miliampers... and the camera will try to judge the remaining capacity
looking for a certain treshold voltage. And the voltage variations here
should be small - and measured in actual use, so this voltage is not the
one measured with ordinary meters. This measurement is made in presence
of a demand.
How soon this specific camera will say that particular battery set is
depleted? It will depend on a whole set of circunstances, but I'm
positive there will be cases such as yours, William. Because that
particular set feels better charged to the camera, as under its present
demand the voltmeter stays in the green zone. I'm willing to bet some
cents a different set of higher-rated batteries may endure a little
longer if you use the flash more, or keep shooting at a faster rate, or
the temp gets a little higher. Let's not forget the batteries in
question may be good for other cameras even after being pronounced dead
by one.
Each and every eletronic gadget has its own signature, about using
energy. Some use much energy to power up, than very little to remain in
operation. Those different uses will drain different batteries in
(guessed right) different degrees. Static tests made with
constant-demand dummy loads will never get the same results, even if
they're made by unbiased people. So both lab curves AND real world
results by observing people with the same gear are important tools to
find out which batt will work better.
If the amount of energy in those things would be equal to the amount of
energy used discussing their use... :-)

I'm with you, Charles.
I've tried numerous brands and the Eneloops have proven to be far
superior to any of them in practice.
If others have had different experience, fine. Use what works best for
you.
Having said that, I'm impressed with the non-rechargeable Energisers
that came with the K200.
I used a few different brands/ capacities of NiMH bateries with my
istD before going to non rechargable lithiums.
I actually didn't see much of a correlation between MaH capacity and
number of pictures taken.
The best performance I got was with some 1700 or so MaH batteries,
which performed far better than the 2400 (IIRC) MaH batteries that I had.
