Agree on the Ballistic Turret- both of mine immediately went and were replaced with an MOA labelled cap. I feel these are more future-proof than true custom (distance labelled) caps, eg a simple change of projectile forced by unavailabliity.

As for parallax and "focus" issues, I think you need to do a bit of reading. These are not same. Young eyes with maximum "accommodation" ( the tech term for ability to adjust focus with varying distance) cannot overcome parallax issues. Parallax causes aiming errors which become important obviously at longer ranges where there is far less leeway for error, esp in wind. You need everything going your way. I'm also a F-Open shooter so am acutely aware of these things.

BTW, the amount of parallax error at any given magnification does not vary with the objective diameter. If your 18X scope has a 40 or 56mm objective, there is no difference in that variable.
