The thing about those Sony guidelines is it almost certainly is referring to target framerates. BF1 has a 60 fps target on both Pro and standard but the reality is far from the target in 64 player conquest. In my mind, as far as Sony is concerned BF1 standard and pro run at the same target framerate, so all is good, even if the drops are severe and constant on the standard and less so on the Pro. I think that is also why the worse performing PS4 Pro games. They aren't allowed to target a lower framerate for enhanced mode compared to the standard, so as long as they both target 30 their good, even if the performance is less consistent.
