As you've seen for example, in all normal power resolution tests it provides a way to compare any one size binocular to another.  All it takes is a review of the reams of data I've posted on that subject to see the relevance to that effect.And here at high powers, whereas a 50mm binocular may be found to reach max at ~70x, a 40mm binocular may be found to reach max at ~50x.  Comparing these two in any way would be difficult unless you choose a common denominator. It works well for both those instances.  This is not a means to find the max.  It provides a means to compare one max to the other across a variety of binocular powers.  I thought you would have understood that by now from what I've written and the discussions we've had in the past, or perhaps you have never pulled that out of what I've written. At any rate, you will find that in all the detailed explanation I've posted on this subject.  edz</blockquote>
