I doubt very much that a comp shooter opens a new bag/box of brass, does nothing to that brass, and loads them up and goes shooting for record. I don't even do that for my hunting rifles. All brass gets neck sized, to my specs, then run through the mandrel. I chamfer case mouths, but I do not trim new brass, it all grows at different rates, so I fire it once and then check. If I deem it necessary, which is rare, I will skim cut new brass for a .001" cut just to see where it's at, but not on a production rifle, rarely any point doing so.
My new brass that will be formed into an improved chamber all gets annealed first before any steps in sizing are done.
I have learnt this is the most efficient way.
Cheers.
