Apologies for being away for a while - I have been busy at work.   
 I have to say I disagree with much that has happened whilst I was away, as it seems that unconfirmed statements are being considered for the article.  I also disagree with much of the article as written by Arzel.  I have already pointed out several factors in my analysis, which appear to have been ignored.  I feel that it is not beneficial to work solely on Arzels version, but instead to work on a 3rd PROPER official version that can be adopted by Wikipeda and is agreed by all.   

 I shall make a further comment below about the content of the article that is being considered.
