I don't care at all. I use the little lee hand held case trimmer and cordless drill. I can trim cases almost as fast as I can measure and sort them. So I just do it while chillin by the fire with a towel on my lap. I don't measure squat. Just make them all the same. Other than a little neck tension change I don't think it matters much.
Neck turning? Now, that matters for getting another quarter inch out of a great rifles groups. Not case length.
