temps and thier influence on hatch time

[NorthernRegius]

I was wondering on the average how the temperature the eggs are incubated at affects how many days it takes for the babies to start pipping?

I have had mine incubating at about 88.5 avg. I am guessing they will hatch at 55 days. Is this about right?

Could some people post thier temps and the time it took fot the eggs to pip on thier own at that temp. Or at least the first baby to pip if you are a cutter. Id like to see what varience there is.
Thanks

This is the temp I use & day 55 is about right +/- a couple of days. In the last 4 years the earliest for me has been 53, latest 60. I don't like to slit the eggs until at least one pips, but if no pips on day 58 I will slit them- I do NOT cut gaping holes in the eggs, a slit is all they need.
