This has been true since 10.2x.
There will always be a list. They will always be adjusted.
Running Rep Perms over and over is a tremendous waste of time.
The only time to be concerned is if it ends with
"Repair Pernissions cannot be completed."
Read these, as well.

Thanks so much for posting back. Actually, I wish they had never named it "Permissions Repair." I'm pretty much a non-geek (LOL), but it's been my understanding helping here over the years, that the "List" is not of "Errors." As I understand it, they're more notations for the engineers. They change with the cron thingies, or the full moon.
Anyway, 10 years ago, repairing permissions were the be-all end-all of what one had to do to maintain a healthy Mac. I think for the past 5 years or so, it's not so much. Regardless, I think it's a good idea to do this after a major OS upgrade. Then forget about it til after the next one.
Just my two cents. Glad you're here, and welcome aboard!
