That's a landmark study, for me anyway. I've read in so many places that 
multiple exposures will not create the same exposure as the product of the

steps due to latency issues. I believed it. But something else was 
happening. I attribute the product difference of many short steps to the 
inconsistency of using a Time-O-Lite (which I had marked in F-Stops with 
only modest success and some real inconvenience.) But now I have the 
Darkroom Automation F-Stop timer. Very cool. Thanks again.
