I agree in a hunting application, this is about target.
In PRS, or other target shooting of unknown distance, FFP is mandatory to range your target (or game, if hunting).
I only see disadvantage in FFP when shooting ELR target at known distance.
Nobody serious ranges their targets in PRS with their reticle. The unknown vs the known distance is not where the disconnect lays.
The disconnect lays between certain age groups that only know what they know who are stubborn about what they know…because.
Now to explain the FFP, it's "better," for those that use the reticle as ruler. Again, not for ranging, but for shooting. Follow up shots are universal. In competitive sports, or in combat and hunting. Things don't always go down first shot, shots get missed regardless of how close or far you are. **** happens.
Secondly, once you have you're elevation, most people I know ( who shoot professionally not Palma and not BR) will hold wind. This has an expansive reason that requires its own response but to keep it short, because wind is not constant, and because it's better to play the wind change. People who know what they are doing bracket the wind.
This is easier translated to the scope on a hold, and holds require and accurate reticle. Generally speaking, one is not using the center reticle for any of this. Good reticles in ffp imo should a floating center dot anyways. For the sake of a good zero. But I digress.
For advance shooters, especially those that come from a legitimate sniper background, will be some of the few people experienced with movers. Samething as wind, you'll be using the reticle, usually with dope for tracking and ambush right? (Rhetorical, the answer is yes)
So, a FFP in the hands of someone that prefers to use particular skill sets: it's the way to go. I've never heard anyone in real life complain they missed a deer or washed out of sniper school or dropped points in a competition because the reticle was too thick. Maybe in BR but…I don't care what bench shooters do, myself.
While aim small miss small is a great mantra, there are reasonable limitations to it and is a more suited concern for someone trying to shoot a small pretty group. I don't find pretty groups super useful compared to a single shot into a vital area. Which is a large area.
