RE: 1/3 stress increase for 5 psf interior wind load

....they should be proving (to you) that their substitution works. My 2
cents about temporary load related reduction: if there are at least two
transient loads acting on the same member, then reduction is acceptable
because of the low likelihood that such a combination will actually occur.
In your case, lateral load to the wall (regardless of the source) exists by
itself.

Have a great day.

This really pisses me off. I guess I am not the only one who has had metal
stud guys just lighten the gage of the studs at their leasure. The AISI code
is very tedious, I do not enjoy going through the exercise of proving that
their substitutions work. ARGHHHHHH ! ! !
