Maybe not set it and forget it but 452 and BCYX are pretty darn close. And that is nice. For years I kept a ruler where I hung the bow but no longer need to. I haven't checked the brace on my current shooter in weeks, months maybe. I made the string in January. Somehow it was exactly the correct length when I put it on. I gave it 4 turns a few weeks after I made it. Haven't measure it since. It could maybe us a twist or two but it never really seems to change enough to matter.
Normally I would put a new string on with minimal twists and let it sit overnight to set the loops really good, then twist it up to brace. I also made a sting stretcher, but I think it is a waste of time with some materials.
