and reviewed my original thoughts in the light of my findings. I then re-posted my modified conclusions.

I can see no benefit in posting information which I already know to be incorrect. It would serve only one purpose...that which you apparently think is a valuable contribution to this site, and which I do not.

And your opinion should prevail because...?

So, whilst I have it within my limited power to delete information which although posted, I immediately realise is wrong or even dubious, I will continue to exercise that power.

If the information has been widely viewed and/or responded to before I realise my error, or someone else points it out, I will strike it, or update the node identifying that the post is in error--as you will find many examples of all over this site.

But in the specific case of instantly realising the error, or even suspecting that it may be in error, I will continue to withdraw that information until I have verified it, or corrected it.

One other question. Why is it that you feel the need to "ridicule" and insult ("Are you so dense")? Is it not possible for adults to have a disagrement without resorting to that?
