...it is recommended to keep the guitar between RH 60-80 from the luthier. Anything lower for long period may have a chance to crack.
it is quite high, compare to most standard RH 45-60 suggestion.
I've wondered the same about Hauser guitars. I agree it doesn't make obvious sense.
The most likely reason I can see is that previous Hauser generations had less control over their workshop climate than we have today, so it's an aspect of their tradition, like a secret sauce. Today they might choose to control the climate in their shop the same way it used to be done, or at least to keep the RH within a range that Hauser 1 would have worked in.
If that's not it, then maybe their hygrometers read on the high side. Something about the way they are/were calibrated, or the type of element inside them ....
