Yeah, 78-79% is close enough. If it's building condensation inside, then either it's not ventilated enough (are there vents you can open? They should be wide open), or your hygrometer isn't calibrated correctly. Let's just keep it like you have it (except open vents if they're closed), as best you can, and move forward. It's too late to check calibration etc. now.
Poultry eggs can hatch anywhere from 2 days before to 2 days after the "hatch date". So the one that's pipped could be just an early hatcher, and the others could be on schedule. If Wednesday is hatch day, then most of the pips should start appearing tomorrow. Your little guy, pipped today, should hatch by tomorrow morning.
The date of collection doesn't affect the date of hatching; it's the date you started incubation that matters. Count the first day you set the eggs as Day 0, and the next day is Day 1, and so on.
'Hatchability' is prime to set eggs that are no more than 5 days old. It's still excellent for eggs as much as 10 days old, but starts to drop severely after that, up to about 30 days old when they're pretty much duds (but still good to eat).
Just a note: Check your eggs for pips on the bottom. If you find any, turn them right side up so they don't drown in their own fluids.
