... All the EV talk in the world doesn't matter, but since others are making it an issue: f16 for 8 sec is listed as EV = 5, (http://en.wikipedia.org/wiki/Exposure_value), and this is a commonly used setting for landscape, foaming water etc. And, Photogs like Dan Cheung have reported consistent under-exposure using the 5DIII. That too is interesting.

Except it is a serious factor in whether and how much the meter would be incorrect for any given situation. In fact, it is THE factor for any given situation. The problem is we're talking about reality here. If you need to have the camera lit to 20EV to get a 1/3rd stop error on the meter, you're not realistically going to do that in the real world ever. So yes, what you're shooting, and how bright the area you're shooting from really does matter.
So as to your Ev 5 scene, you're going to have to provide more than just "this is used for..." how bright is the actual environment the camera is in? This is crucial to determining whether there's the potential for a metering error. If the camera is in EV12 and you're NDing down the scene to EV5 with a f/16 lens, ya, you're probably going to see a problem with a 5D3. If the camera is in EV12 and you're NDing the scene down to EV5 but using an f/4 or faster lens that doesn't require stop down metering, you're not going to see an error at all. This has been generally born out by my experience in the field with and my testing of my 5D3, and I don't believe my camera is an outlier in any special way on the good side.

As am I. I'd much rather they promptly acknowledge things, even if they ultimately do nothing, than not acknowledge it at all.
