The thing is, everybody's setup is a little different and can yield different results. Justin has hatched 100s of clutches so he knows with certainty when his are ready. My clutches have actually all hatched early between day 51-55 and that was at 89. I lowered to 88 this year so we'll see. But then I know breeders who do 89 and theirs don't pip till after day 60. So until you hatch quite a few clutches and know exactly what is normal for your setup, you really don't know when they are going to be ready. Once one pips, then you know. Imo it's just better to be patient and safe rather than possibly do harm.
Just one other note of caution, I'm glad the one you were worried about is moving but keep in mind, you actually don't want them moving around in the egg, especially since you're not sure how far along they are and could very well still have an egg snack attached. That could definitely cause complications so I wouldn't go poking at them. Just take a peak a couple times through the day to check on them but for the most part you want to leave them alone. I understand how hard it is lol, but just try to be patient and they'll all come out when they're ready.
Make sure to post pictures once they are out, I can't wait to see them!![]()
