Let me send Park a question about dry v lubed threads and their table. In the past, they've replied to my queries pretty quickly. I'll let you all know what they say.
Great! Thanks for doing this. I hope you get a response soon.
As for greased or not, while you get more tension in the fastener with less applied torque when using grease, I think there may be advantages to un-greased in terms of a bolt loosening. But, I too, tend to grease unless specifically instructed not to do so or it is obvious for some reason to avoid grease (around disc brake rotors for example).
