Interesting point, maybe someone with a *ist D can execute a multiple exposure 
of a static subject from a sturdy tripod at EI 3200 and compare the output 
noise with a single exposure?

Other than noise reduction or shooters requiring direct print from RAM cards I 
can't see any other real use for the multi-exposure function.
