Batching Projectiles

So, I heard some guys batch their projectiles to weight, some batch to bearing surface and others base to ogive. What do you guys do? If you do?

I batch base to tip. Then trim in 4 thou batches
The I point
The I batch by bearing surface after all of that

I have then done some weighing of projectiles after they have been batched that way are they are really close.

I am sure you can do more but that all I do that servers me well.

I normally batch from base to ogive. My line of thinking was if I had that consistent measurement between projectiles when seating them, I would have the same measurement of projectile in the case neck. And that should give me very similar neck tensions if I've got my case prep right. Would that be anywhere near being correct, or am I running up the wrong path again?

Bryan Litz advises base to ogive and his advice is sound no bs.

I weigh and sort as I find 85% fine and within parameters.
However I usually find one which is way out in every 1000.
I try to buy them in 1000 lot minimums so they are all one lot.
