I guess this confirmed my thoughts.
Seems i would benefit to keep the parallax closer to the longer ranges.
What i have done before when shooting multiple targets quick with reticle holdover (with HK mr762) is to put the parallax to 3/4 of furthest target. All targes looks clear trough s&b pmII...
So thinking about parallax and figuring out how the physics works.
And seems like the maximum parallax error depends on objective size and parallax setting.
If for example i would engage multiple man sized targets from 100yards to 1000yards as quick as possible without adjusting my parallax...
