We as fans know what lightspeed skipping is, but without the prior scene to give us context of it, it’s just the Star Wars universe usual technobabble. To the average viewer, it doesn’t actually mean anything more than compressor this, subalternator that. I agree that it’s better for the pacing of the scene and for the characters to have the full dialogue.

edit; nevermind, I misunderstood and thought we were discussing Rey and Poe’s talking about lightspeed skipping (which I do still think is probably less jarring to just leave in even though we don’t see it.) I don’t particularly think the actual act of lightspeed skipping should stay. It’s just pretty visuals with some absurd implications.
