For me, I consider if the light will be impeded in any way: if the layer going 
on top of this one I'm working on has any color pigment at all or if I'm  going 
to add something that will block any light, then this layer needs to be fully 
cured before moving on. 

Thinking along these lines, if any layers I'm going to do above this one are 
crystal clear, I figure the light can penetrate and this layer will be fine. 

Working like this can save a few minutes and I have never noticed any 
undercuring breakdown.
