I guess that's only because the images were so blurry and indistinct, anyway, that the edges weren't clearly defined from the get-go. It occurs to me to wonder if .... since you're dancing around minimum pre-shrink, minimum pre-stress, or "virginity," so to speak, it might make a difference if the pre-shrink wasn't HOT. A while back I tested a looong preshrink in room temp water vs. the HOT short preshrink that's the norm. I found that the long room-temp soak gave the same amount of shrink that the short hot soak did... I don't remember the times, tho I could probably find them in Post-Factory, but it occurs to me to wonder if the room temp soak might "raise the nap" or rough up the paper less than the hot. Of course you seem to be doing OK the way you're doing it, & no need to fix it, if it ain't broke, but I mention the thought, should a snag arise. J.
