Incubating Day Count, No such thing as a silly question right?

Thank you everyone for your help.
I too was pondering this question and I thought it had to be precise when it got to those last few days so I was fretting a bit.

I should have chicks hatching in 3-4 days.
Decided to split the difference and am going to put the eggs into shut down this evening.

IMO, the lockdown can vary by a day each way with no worries. Just get the humidity up before the first pip.
