> "We're going to make PSC less onerous and stressful by only doing it once a year!"

There's something interesting going on here. I agree that people will probably perceive annual PSC as less stressful than semiannual PSC. But even there, some people might not.

And there is a point where more frequent is very clearly less stressful. If you did PSC once a week, it wouldn't be cause for stress, it would just be something you did every week.
