Can I ask that those people take a look at the ongoing situation, summarised below.
I'm sorry but my eyes just glaze over when I try to approach this. In order to give an impartial judgment I'd have to at least:
1. Educate myself on this relatively obscure Australian technical question, preferably from good sources outside of Wikipedia.
2. Carefully study the editing history of the article.
3. Wade through a talk page which is currently archived in 8 volumes.
4. Chase down any relevant comments made on talk pages of users involved.
This is just more effort than I'm willing to spend on this matter.
I'm sorry and I'm writing this to explain since I'm sure your request is made in good faith.
Regards, Haukur
