you can always add more edges. adding edges doesnt change the UVs, so you can make a duplicate of your model, add more edges, use the 3 key to see how much it shrinks, and keep adding edge loops until you're done.
tbh, i don't think it really adds much benefit because the maps you get still seem to work with the original model. But then, I'm just trying it out now on my model
that's a "Ch" pronounced as a "K"
