>> I'll give these a bit yet
Totally!
Someone with a clue is likely to chime in pretty soon, and they may contradict me.
What I do when I've over-watered a tray of seeds (which is "usually") is to prop the humidity dome up a little, on a pencil or a chopstick, to let humidity escape gradually. If the dome was beading up with water, a crack probably leaves the humidity near 100%.
Eventually I take the pencil away to see if water still condenses in big droplets.
I recently learned to "wick excess water away" using a pad of cotton flannel. That trick just delighted me so much that I wrote an article:

Before that, the only seedling that survived my treatment were those very resistant to severe over-watering. Now, I can start seeds that are only moderately resistant to overwatering!
You've already got me beat: you only MIST your seedlings more often than necessary. Using the gadgets I love so much, I usually drenched them much more often than necessary, which I guess is "never".
I should probably ask Dave to create an "incessant over-waterer" micro badge. Something like a few damped-off seedlings rotting in a puddle.
I think I developed my over-watering addiction when I learned decades ago that when you plant a shrub or a tree outdoors, you need to "water it in" very heavily, to settle the soil I guess.
Usually I'm detail-oriented enough to make a distinction between a tree and a seedling, and between "outdoors in soil" vs. "indoors in a plug tray".
But not on this issue, it seems.
