Incubation Humidity...why so high?

[Quiet Tempest]

I was just wondering why everybody incubates eggs at near 100% humidity when other people are maternally incubating with success. I'm not a herpetologist and seem to be missing the thoughts behind this process.

Can anyone shine the light on it for me?

I'm maternally incubating. My females' tubs are reading between 70% and 80% humidity right now, but you have to consider that the eggs are kept snug within the mother's coils where the humidity will be even higher.

If you maternally incubate, you really don't want to increase the entire enclosure's humidity to the same levels you would in an incubator. It could cause problems for the female.
