Objective comparisons are not facts...
Machines are objective, but don't always tell us what will happen in the real world. Exit pupil is a mathematical number which truly is worthless. Like one of our .com friends posted, and I paraphrase:
"A brightly lit blob is still a brightly lit blob."
Ringman,
The exit pupil is not a worthless arbitrary mathematical ratio/number but in some sense a number that describes the aperture of the human eye as an optical system. Matching the scope's exit pupil to your eyes pupil maximizes the total light received by your eye and this assumes your eye is a typical eye and your retina's rods/cones can utilize the available light delivered from an increased exit/entrance pupil. Our eyes are atypical but this fact does not invalidate the physics behind the entrance pupil of the average human eye.
To your point, an increased pupil might make things brighter but for sure will make things smaller and I will not be the guy that argues against the resolution vs brightness trade, aka "a brightly lit blob is still a brightly lit blob."
After all, "a brightly lit blob is still a brightly lit blob..." but also "a high resolution picture is useless when the lights are off..."
