This was a one-off, timestamp on the file says I did that on 26 June.

We had a discussion last week in the office which boiled down to pretty much what you describe here, as an alternative to 'eyeball' data. I expect more in this space soon :) Cheers and many thanks to all our ambassadors for the great work they are doing! Emile
