This is incredibly valuable intel on Meta's post-purchase tracking! The PES system explains so many mysterious CPM spikes we've seen after scaling certain offers. The 30-50% penalty is brutal but makes sense from Meta's perspectiv - they're protecting user experience at the advertiser's expense. The catalog sentiment zoning strategy is genius, especially the red/yellow/green SKU classification. Have you noticed if certain verticals get harsher PES treatment? Seems like supplements and high-ticket items would be more vulnerable to buyer's remorse surveys.
