As for the flattest trajectory, that's not necessarily true, because it depends on what distance we're concerned about. If 300y itself is the goal, then the 36y will theoretically be very close to POA at that distance. A more common zero is the 50/200, which is still very flat out to 300y. I run a true 200y zero, and my POI @ 100y is +1.1" and POI @ 300y is -6.4". The 50y will produce similar results.
In comparison, using a ballistics calculator, the 36y zero produces a POI +3.2" @ 100y, +4.3" @ 200y, and -0.1" at 300y.
I think it's a balancing act between prioritizing the first 200y, or 200-300. In essence, they're all very effective and infinitely better than the 25y "zero".
I think you will be well served with the 36y zero, but for me, the first 200y is a higher priority so I prefer to zero accordingly.
