apex legends uses 0% monitor distance (matching at cross hair for ideal tracking ) (it isn't actually broken when set to default scaling , most users aren't used to it scopes getting slower with high zoom this can feel off )
the per scope scalars have some flaws to them with different zooms to them so it is far better to stick to a 0% type matching
cod defaults to 1.3333 /133%vertical monitor distance these days , but gives you the option to use 0% too

^this would be 0% match at 0.7 ads

this would be 133.333% vertical^ at 0.7
0.7= 70% /1.0 = 100% etc
the 133.33333% vertical can be replaced by any method of scope scaling you prefer
0% hor / vert / 100% hor / 177.78 %vert and plenty more multiple of those
are mentioned i the instructions
