Mine are also incubating at 89F, so chances are your eggs will pip closer to day 55 than day 60.

Condensation on the lid can drip onto the eggs--this is an issue with both substrateless and vermiculite/perlite incubation. When you go to lift the box out, tilt it slightly so that water on the lid runs down instead of dripping. (Obviously, this doesn't work if you're using substrateless--other options include putting a piece of paper towel over the eggs, or just being careful to dab them with something absorbent if water drips on them).
