Hey Matt,
I don't think this will answer your question but I did go through pretty much the same dilemma last year that you are having now so I thought to reply.
Out of a 6 egg clutch, 5 pipped on their own in a timely manner. (Sorry I don't recall the incubation day and I wish I would because I also incubate my eggs at 88 degrees). Anyways, there was one left to pip and I was leaving for vacation in two days. So I decided to cut the remaining egg. (Also my first time doing it. Not to difficult BTW). The little bugger was out and scooting around the egg tub the very next day after I snipped.
So here is my opinion... If you would rather have them pip on their own, don't cut the eggs until you absolutely have to. From my experience, it only takes the babies a few days to come out of the eggs after they pipped.
Hope this helps just a little. Keep us posted on what you decide to do and how it turns out. Just curious.
