Default Real World Ceiling Fan CFM

Has anybody done testing on delivered CFM of ceiling fans? Energy star has a test room where the blades are 40 5/8" from the ceiling, but this rarely happens in living rooms. Perhaps manufacturers should list actual CFM output at various mounting heights instead of the laboratory 40 5/8" that almost never exists in the real world.

How is CFM affected when installed at the default 12" from the ceiling? When used with taller ceilings, does installing a 12", 18", or even a 24" downrod significantly affect delivered CFM?

How does blade diameter come into play? Are smaller fans "more tolerant" of being mounted closer to the ceiling? Is a 42" fan a better choice than a 60" for a typical 8' ceiling due to limited space above the blades?
