I was scared too...then I just did it. I cut on day 52 and I had to wait until day 56 for pips. I was SOOOOOOO stressed out after I cut them because I was worried they would dry out. I think if they didn't pip when they did, I would have gotten an ulcer from all the stress. So this time around I'm just letting them pip on their own to relieve that stress. It's far better to just be impatient than stress.
