It continues to REALLY rile me that such important specifications as field of view and eye -relief are so commonly over - stated by manufacturers.
There ought to be a LAW against it , backed up by heavy financial penalties.

Perhaps due to your efforts things may eventually evolve toward some sort of solution to the gross misinformation that seems to exist regarding manufacture's binocular specifications regarding FOV. Barry's idea about what criteria or methodology used to determine FOV could well bare fruit. One would think that there would be some sort of industrial standard for this. In the meanwhile Ed you may want to watch out for Chinese hit men.-smile-Keep up the good work guys!

Eye relief seems to vary a bit from spec...and my girlfriend's binos at 6.3 degs have a wider FOV than my 6.6 deg binos.
Give me a break!
So, what do we do about it?

In the case of the Oberwerk 22x100s that I found had a 2.8* FOV, rather than the 3.3* FOV that was stamped on them, I returned them. The FOV was not the only issue with those. They were also optically inferior, and Kevin Buserow even confirmed that when I returned them. But, what also bothered me is that he told me after the fact, that he knew the FOV to be less than 3.3*. He said he's working with his supplier to have them re-labeled. But, in the meantime folks are still buying those with expectations that can't be met. In fact, he's still got those advertised on his website as having a "large wide-angle (3.3° FOV) eyepieces". He should modify that advertising, considering that he knows it to be false.
It does raise the interesting idea that perhaps the eyepieces are 3.3*, but the binoculars aren't. Either way, it doesn't matter, since the 3.3* claim is repeated in the spec chart for those binoculars. It's clearly misleading.
As for eyerelief, we could start a whole separate thread on the binoculars and eyepieces that don't live up to claims.
