Just wondering if the FoV that is listed on a scope as 125' @ 15x and 65' @ 45x, would that equal a linear measurement of 95' at 30x or does FoV operate on a curve? Thanks.

This is my stance from a mathematical point of view knowing limited info about FOV given that the numbers you provided are correct. Even if the FOV is operating on a curve you would have to be somewhere close to 95' @ 30X. It may be not perfectly linear but my guess would it would be pretty close

Yes, it is a linear relationship, expressed as either an included angle or width at X distance.
