Here is a quick time lapse I took of one of my clutches-compressed 68 days into less than 4 minutes.
First pip @62 days...last one hatched @68 days.
Temperature fluctuations are standard for my time lapse incubator. The variations have historically had no impact on my hatch rate.
TLDW (Too Long Didn't Watch):
8 eggs
7 hatched (all perfect)
1 failed to develop
Oh yes, and for those easily triggered: Relax: Both eyes are perfect on the Super Lesser. I've never produced one with any defect using Het x Het...
