Humidity

[chickens really]

I think it has forced air because it has a fan going.

Then during setting Shoot for 40% Humidity and at lockdown 60%...

The cover to the incubator has a lot of condensation with a hand towel and sponges to help with the humidity. Would there be a chance of it not showing higher humidity?

Yes, my RCOM doesn't read higher than 70%.

Yes, when I asked if there was condesation, i was wanting to verify that the %RH had reached saturation! That means nearly 100% RH.
That is to high even for "lock down"....the water droplets could fall down on the eggs and if they fall on the pipped area, I could drown the chick.
You need to get a separate hygometer, calibrate it and not rely on the units hygrometer to give you accurate humidity levels.

I don't think it's as simple as that... Something about dew point?

Your correct Kathy, I didn't want to go into a lengthy detail of why the condensation was forming, That's a whole other subject. It was a simple way to ask about the humidity and hygrometer accuracy.

So if one has an incubator in a room that's 80 degrees (like mine is right now, lol) the point at which condensation on the lid forms will be different than someone whose room is at 60 degrees, right?

That's true to a degree...lots of other factors are involved including the temp of the room inwhich the incubator is located, as well as the ambient humidity in the room.

When air cools, the capacity of the air to hold water vapor is reduced and the %RH will increase. If the air temp falls below the saturation point of 100%RH then the water vapor will condense.
Cooler air entering the bator holds less water vapor than a warm ambient air, therefore, the points of condensation occurring would be different.
This is why surface area of the water reservoir is more important than volume of of the reservoir.

Yes, my RCOM doesn't read higher than 70%.

Surface area is most like the reason why your %RH won't go above 70% or it could be that the units sensor isn't capable of reading higher percentages. Idk, I don't own a RCOM but 70%RH is more than adequate.
