Thank you Andrew. I think you are correct, issue 1179 is the same
problem. I can see now that the API geocode of "CA6 5TR" matches
maps.google.co.uk's position for "CA6 6" and "CA65TR" matches "CA6 5".
So that's the off by one issue, and the other thing I highlighted is
probably caused by the use of output=embed.

So am I correct in thinking that due to license restrictions Google's
geocoding results are less accurate for third parties using the API?

In conclusion for me I think the inconsistencies are caused by the
'off by 1' bug, which is further obsfucated by the different handling
depending on whether a space is included in the request or not, and
the inaccuracies are caused by reduced accuracy due to stripping off
the last two characterse of the postcode for API based requests.

Issue 1179 was filed about 9 months ago. It would be nice to see it
fixed. I would hope that once it's fixed then the handling of the
postcode with or without the space would become consistent as well, or
does that merit a separate bug request? I agree that the postcode
should be presented with the space, but if the resulting location
differs then it becomes an issue to decide which to use.

Cheers,
Mark
