To the Hatcher Tonight! Humidity Question

[bigredfeather]

I have 37 Dark Cornish eggs going down into the hatcher tonight. This is my first hatch in my Sportsman. I have kept the humidity between 45%-55% for the entire time. Unlike my Hovabator, I can get the humidity up much higher in the Sportsman. What is the ideal humidity for hatching. I have read 80%, but want to see what others think. I have no other eggs in the bator, so that isn't a concern.

Thanks.
