What do you check in HubSpot CRM audits, and which finding gets clients to act fastest?

I'm running CRM audits on HubSpot for a few agency pilots. Right now I check 5 things: • Clean records: duplicates, missing owners, empty required fields • Pipeline and stages: deals skipping stages, stage dates that don't add up • Activity on the right deal: emails and calls logged to the contact, not the deal • Lead source: blank, overwritten, or set by two tools • Stale deals: open deals with no activity in 30+ days For the consultants and agencies here: what do you check that's not on this list? And which finding gets a client to act fastest?
