The power of the scope is actually a rounded up or rounded down number. Who ever puts the specs out has some liberty to do that and marketing has a shot at it also in writing up all the good features of the scope so you'll buy it. If two scopes actually had exactly the same power and same lens size, they'd have the same fov. Some scopes have a "margin" added around the outside edges as sort of a finish to hide the seal between the lens and housing. This can take a little away from the fov if present.
