Aren't Premium Plus passengers prioritized over all economy passengers?
You will be above all non-GS economy customers. UA does not mention GS priority publicly but it does impact this situation.
For business class, GS are waitlisted for PN and non-GS are waitlisted for PZ, but PN >PZ, hence with your PremPlus priority for PZ you are still behind a business waitlisted GS.
