Indeed, perhaps they should take design inspiration from you.

Sorry - I looked at the metropol logo and was blinded by it's hidiousness.
I hate to be the bearer of bad news, but while you were blinded your account must have been hijacked because there are some utterly idiotic things posted on metropol under your name.
That was fixed when TCJ and TCW were produced, on TCF it was always said to mark the *approximate* centre.
Yes - even at a glance, the cross on TCF always looked just slightly to the right of centre.
Out of curiosity, when they finally moved the cross to the exact centre for TCJ onwards, was the change made for a particular technical purpose, or was it just for the sake of precision and not absolutely necessary?
Though the Freeview test card is an MPEG still I believe (not JPEG) and very poor quality...
Some Freeview boxes (like my Humax) show it de-interlaced, that might be what you are experiencing.
No - it is the heavy DCT artefacts that annoy me...
How do I view this testcard?
Go to Freeview Channel 105 ("BBC Red Button"), press yellow, go to any other channel and back to 105, press green, a "Secret" page should pop up, then press green again. (It used to be a bit more complicated, in case anyone remembers the instructions being different and involving a numerical code)

The cross on the blackboard in the picture was always stated as being NEAR the centre of the picture. It was indeed near, but not precise. Having obtained the rescan, we have taken the opportunity of making it PRECISELY the centre of the picture. This necessitated zooming out and panning right a little, which also resulted in a rather better composed picture than the original, giving Carole some headroom, showing her elbow, and the whole of the doll. The colour of the doll's dress is noticeably duller, but is more realistic. The original looked fluorescent, and George admits that the lab tinkered with it for Test Card F. The new picture is also not so sat up or desaturated.
While that doesn't explicitly state any functional
purpose
for centering the cross which is what I was asking, it's still very informative, so thanks for that.

I think that in particular was a case of "because we can" over an explicit purpose. I think the other features of the test card are together significantly more useful than an isolated centre marker.

Yup, that's what I was leaning toward.
The fact that they had
"taken the opportunity"
to centre it suggests they were simply able to change it *if* they wanted, and decided to do so.
