Is FOV linear, and comparable between 2 scopes? See attached. PST has FOV 41.2' at 3x and 8.6' at 15x. LHT has 23.5' at 4.5x and 4.7' at 22x. If FOV is linear, the graph shows they will have similar FOV around 13x, and from 13x to 15x, the LHT will have greater FOV than the PST.
Can FOV be compared in this manner, or does the linear concept not apply?
