No, the scope power does not reflect the actual zoom (like they did in BFV).
The 6X and 7X use the same setting, that's why they are noted in parenthesis. The 12X is using the 10X sensitivity setting, the actual 10X I haven't got yet so it's not added.
Setting the coefficient to 0 will still scale the scopes according to their FOV exactly like in BFV, but you can't compare the scope powers between the games at all.
