Pushrod measurement opinion

You want to keep the adjuster up in the rocker, but too far up and it won’t oil and too far down and it won’t oil either.
Looking at various aftermarket rockers that oil/utilize ball adjusters they all have the oiling hole drilled in varying locations from the underside flat and when using a ball adjuster with a cup pushrod I’m thinking the adjuster initial setting should be set accordingly to line up at a point on the adjuster or based on where the top edge of the cup on the pushrod is vs just a set number of threads or a certain depth, don’t you think?
