Your experience with ice makers is totally different than mine. I
don't notice any difference in running time on mine when it's making
ice versus when it's not.

Noticing or not noticing isn't physics. One has to appreciate
thermodynamics and the heat of fusion to understand why ice making is so
much more energy intensive than making up heat losses through a well-
insulated cabinet or warm air infiltration.

But heat removal is still heat removal as has been pointed out before --
it's only the source and the amount of heat required to be removed from
the water to create an equivalent amount of ice is the same for equal
amounts of water at the same initial conditions. So again, it would
change the magnitude of the numbers, much less effect on the _relative_
results which is the point of the test.
