humidity control in homes

I should think most properly designed, sized, and installed residential-type
whole house humidity control systems could keep humidity within 10% or so of
a targeted RH. I would love to have that in my home. I would remove my
Dampp-Chaser system in a second if I did.

Well, maybe impossible within 5%. Who said anything about that? Keeping RH
within 10% or so of a targeted value is controlling RH. Therefore whole
house RH control is indeed possible and practical (can be a bit expensive
though).
