"If the seed has already 'popped', 2-3 days.
If not, I have seen seeds taken up to 2 weeks to break dirt."

I am sure that has been the case sometimes, or you would not have posted it, but mine have never taken that long? Never more than 5 days at the most. I never soak or paper towel them first. I just plant them directly in wet seed start soil and keep it wet with a sprayer till they pop through. Then I stop watering till the cups are almost totally dry. This is under FLs

"A lot depends upon your temperature. Keep it right around 78-80 degrees F. "

I agree: I keep the house at 71 when the heat is on and 77 when the AC is on. I put the cups on top of a cookie sheet that is sitting on top of a medical type electric heating pad. When the inside temp is 71, I turn the heat pad on low. That raises the soil temp to mid-high 70s. When the AC is on and the inside temp is 77, I just turn off the pad.
