Too many roads in this area seem to have the postcode CF32 9EQ. Check which ones are a mistake.

Check postcode for Hare & Hounds PH. It's got a completely different district compared with OS OpenData CodePoint.

Is number 4 missing? I can see evidence for it in historic Land Registry Price Paid data.

Presumably New Barns Avenue and Rochester Avenue here should have maxspeed=10 mph instead of maxspeed=10 (The default unit is kph)?

Change deprecated highway=byway to observed type (e.g. highway=track). Add prow_ref if signed.

Review road refs. It looks like the roads here may have been adjusted.

Node for SDS has addr:housenumber=180, but the building way beneath it has addr:housenumber=186.

Review unit of maxspeed. Default when not specified is kph, not mph.

Is this hotel still open?
