With stud mount rockers, does it make ***ANY*** difference if you adjust the valves with the lifters pumped up or not as long as zero lash is accurately found with each method?

Usually when I readjust my valves, the first few/several will have lots of resistance (pumped up), and then as I go, the others not yet done will bleed down and when I get to them they will have little resistance. I wondered if this would cause a difference in the preload set on the lifters.
In both instances, I assume that the pushrod seat in the lifter is fully up against the stop (clip) when finding zero lash and not compressed. If this is true, does this mean that both pumped up and not pumped up will adjust the same?
Thanks,
