Fruiting Conditions Confusion

AT this point I have read many posts here and elsewhere about fruiting conditions.

Is the actual goal to cycle between drying out the surface and rehydrating it or just letting in an incredibly small amount of fresh air?

It seems many people are saying if your coir is properly hydrated you never need to spray or fan. Other sources clearly say the process of the surface moisture evaporating and rehydrating it is one of the triggers for fruiting. Also, If you crack the lid you are drying out the substrate and your surface moisture evaporates at some point.

What say you all?
