I'm judging the exposure accuracy based on both how the picture looks  
to my eye and by the histogram display in Camera Raw together. On  
scenes which approach the general case of an average 18% reflectance  
gray, I expect the histogram display to be approximate to a Gaussian  
distibution. I also look to see whether what I consider to be Zone II  
to Zone IX areas of the scene are windowed in the histogram without  
clipping.

It's a judgement call, for sure, but based on my experience in RAW  
conversion processing and subsequent, I know pretty much what I need  
to get the results in my final print. :-)
