I have never claimed to be infallible. Working on my phone it is not easy to type and cross check things, so I don't know which two data sets I confused, but if I did I did.

when I said a fact might have been omitted from an article in the Guardian what I had in mind was nothing to with deliberate distortions or errors. It is simply that every newspaper article will include what they think are the most salient points. There is always a judgement how important a detail is, and if space is limited (or time to write it is limited) a less salient point may be omitted. You may include more and more and more of these points in your article, but the need to publish forces you to draw a line somewhere.
