What is the standard practice for %defattr in spec files when packaging RPMS?

I am packaging a bunch of software using RPM.

Is it a good idea to specifically use '755' (which are the permissions I want for my software on my system) as opposed to '-' in the %defattr section of the spec files?

I am asking because I had '-', but I got 700 for some of my installed packages as opposed to the 755 I was expecting. Thus, I am under the impression that explicitly stating the permission is more reliable. What do you think ?

I'm wondering if it has to do with your umask at the time of building?
Mine's set to 027 and I have never had permission problems after building RPMs.
I only set perms if I need something specific.

That seems to make the most sense. I guess the question now becomes: "How does RPM use the umask to determine the default permission when using '-' for %defattr, and when does this get applied".

I'm going to try to test this myself. If someone already has the answer that would be great.
