I’d care more about repeatability that I would the actual error. I’d take a 4% repeatable error over an error that was 1% and 2% there. I can input the true value in calculator and keep moving.
Also, if I’m going to dial all the time, I’m going to spend the extra cash for a premium optic known to hold up over time. Otherwise I’d just use the tree and hold everything.
Example: when I recommend say an Athlon Argos for a budget nrl22 rifle, I tell people to zero the rifle and then don’t touch the dials. Just use holds. I don’t trust a $300 optic to dial all day everyday and be consistent.
